The part is available in a 44-terminal MQFP and a 44-lead PLCC.PRODUCT HIGHLIGHTS The AD7891 is a complete monolithic 12-bit data acquisition system that combines an 8-channel multiplexer, 12-bit ADC, 2.5 V reference, and track/hold amplifier on a single chip. The AD7891-2 features a conversion time of 1.6 ms and an acquisition time of 0.4 ms. This allows a sample rate of 500 kSPS when sampling one channel and 62.5 kSPS when channel hopping. These sample rates can be achieved using either a software or hardware convert start. The AD7891-1 has an acquisition time of 0.6 ms when using a hardware convert start and an acquisition time of 0.7 ms when using a software convert start. These acquisition times allow sample rates of 454.5 kSPS and 435 kSPS, respectively, for hardware and software convert start. Each channel on the AD7891 has overvoltage protection. This means an overvoltage on an unselected channel does not affect the conversion on a selected channel. The AD7891-1 can withstand overvoltages of ±17 V.APPLICATIONS Data Acquisition Systems Motor Control Mobile Communication Base Stations Instrumentation

The AD7417 and AD7418 are 10-bit, 4-channel and single-channelADCs with an on-chip temperature sensor that can operate from asingle 2.7 V to 5.5 V power supply. The devices contain a 15 μssuccessive approximation converter, a 5-channel multiplexer, atemperature sensor, a clock oscillator, a track-and-hold, and areference (2.5 V). The AD7416 is a temperature-monitoring onlydevice in an 8-lead package.The temperature sensor on the parts can be accessed via multiplexerChannel 0. When Channel 0 is selected and a conversionis initiated, the resulting ADC code at the end of the conversiongives a measurement of the ambient temperature (±1°C @ 25°C).On-chip registers can be programmed with high and low temperaturelimits, and an open-drain overtemperature indicator (OTI)output is provided, which becomes active when a programmedlimit is exceeded.A configuration register allows programming of the sense of theOTI output (active high or active low) and its operating mode(comparator or interrupt). A programmable fault queue counterallows the number of out-of-limit measurements that mustoccur before triggering the OTI output to be set to preventspurious triggering of the OTI output in noisy environments.An I2C® compatible serial interface allows the AD7416/AD7417/AD7418 registers to be written to and read back. The threeLSBs of the AD7416/AD7417 serial bus address can be selected,which allows up to eight AD7416/AD7417 devices to be connectedto a single bus.The AD7417 is available in a narrow body, 0.15 inch, 16-lead,small outline package (SOIC) and in a 16-lead, thin shrink,small outline package (TSSOP). The AD7416 and AD7418 areavailable in 8-lead SOIC and MSOP packages. Product Highlights The AD7416/AD7417/AD7418 have an on-chip temperature sensor that allows an accurate measurement of the ambient temperature (±1°C @ 25°C, ±2°C overtemperature) to be made. The measurable temperature range is −40°C to +125°C. An overtemperature indicator is implemented by carrying out a digital comparison of the ADC code for Channel 0 (temperature sensor) with the contents of the on-chip TOTI setpoint register. The AD7417 offers a space-saving, 10-bit analog-to-digital solution with four external voltage input channels, an onchip temperature sensor, an on-chip reference, and a clock oscillator. The automatic power-down feature enables the AD7416/ AD7417/AD7418 to achieve superior power performance. At slower throughput rates, the part can be programmed to operate in a low power shutdown mode, allowing further savings in power consumption.Applications Data acquisition with ambient temperature monitoring Industrial process control Automotive Battery-charging applications Personal computers

The AD5291 and AD5292 are single-channel, 256-/1024-position digital potentiometers that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices are capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1% end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory.The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.The AD5291 and AD5292 device wiper settings are controllable through the SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 20-TP memory. The AD5291 and AD5292 do not require any external voltage supply to facilitate fuse blow, and there are 20 opportunities for permanent programming. During 20-TP activation, a permanent blow fuse command freezes the wiper position (analogous to placing epoxy on a mechanical trimmer).The AD5291 and AD5292 are available in a compact 14-lead TSSOP package. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +105°C.APPLICATIONS Mechanical potentiometer replacement Instrumentation: gain and offset adjustment Programmable voltage-to-current conversion Programmable filters, delays, and time constants Programmable power supply Low resolution DAC replacement Sensor calibration

The AD5560 is a high performance, highly integrated device power supply consisting of programmable force voltages and measure ranges. This part includes the required DAC levels to set the programmable inputs for the drive amplifier, as well as clamping and comparator circuitry. Offset and gain correction is included on-chip for DAC functions. A number of programmable measure current ranges are available: five internal fixed ranges and two external customer-selectable ranges (EXTFORCE1 and EXTFORCE2) that can supply currents up to ±1.2 A and ±500 mA, respectively. The voltage range possible at this high current level is limited by headroom and the maximum power dissipation. Current ranges in excess of ±1.2 A or at high current and high voltage combinations can be achieved by paralleling or ganging multiple DPS devices. Open-drain alarm outputs are provided in the event of overcurrent, overtemperature, or Kelvin alarm on either the SENSE or DUTGND line.The DPS functions are controlled via a simple 3-wire serial interface compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards running at clock speeds of up to 50 MHz.APPLICATIONS Automatic test equipment (ATE) Device power supply

The AD736 is a low power, precision, monolithic true rms-to-dc converter. It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs. Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty-cycle pulses and triac (phase)-controlled sine waves. The low cost and small size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD736 offers higher accuracy at an equal or lower cost.The AD736 can compute the rms value of both ac and dc input voltages. It can also be operated as an ac-coupled device by adding one external capacitor. In this mode, the AD736 can resolve input signal levels of 100 μV rms or less, despite variations in temperature or supply voltage. High accuracy is also maintained for input waveforms with crest factors of 1 to 3. In addition, crest factors as high as 5 can be measured (introducing only 2.5% additional error) at the 200 mV full-scale input level.The AD736 has its own output buffer amplifier, thereby pro-viding a great deal of design flexibility. Requiring only 200 μA of power supply current, the AD736 is optimized for use in portable multimeters and other battery-powered applications.The AD736 allows the choice of two signal input terminals: a high impedance FET input (1012 Ω) that directly interfaces with High-Z input attenuators and a low impedance input (8 kΩ) that allows the measurement of 300 mV input levels while operating from the minimum power supply voltage of +2.8 V, −3.2 V. The two inputs can be used either single ended or differentially.The AD736 has a 1% reading error bandwidth that exceeds 10 kHz for the input amplitudes from 20 mV rms to 200 mV rms while consuming only 1 mW.The AD736 is available in four performance grades. The AD736J and AD736K grades are rated over the 0°C to +70°C and −20°C to +85°C commercial temperature ranges. The AD736A and AD736B grades are rated over the −40°C to +85°C industrial temperature range. The AD736 is available in three low cost, 8-lead packages: PDIP, SOIC, and CERDIP.PRODUCT HIGHLIGHTS The AD736 is capable of computing the average rectified value, absolute value, or true rms value of various input signals. Only one external component, an averaging capacitor, is required for the AD736 to perform true rms measurement. The low power consumption of 1 mW makes the AD736 suitable for many battery-powered applications. A high input impedance of 1012 Ω eliminates the need for an external buffer when interfacing with input attenuators. A low impedance input is available for those applications that require an input signal up to 300 mV rms operating from low power supply voltages.
