The AD845 is a fast, precise, N channel JFET input, monolithic operational amplifier. It is fabricated using Analog Devices' complementary bipolar (CB) process. Advanced laser-wafer trimming technology enables the very low input offset voltage and offset voltage drift performance to be realized. This precision, when coupled with a slew rate of 100 V/µs, a stable unity-gain bandwidth of 16 MHz, and a settling time of 350 ns 0.01%-while driving a parallel load of 100 pF and 500 Ohm- represents a combination of features unmatched by any FET input IC amplifier. The AD845 can easily be used to upgrade many existing designs which use BiFET or FET input hybrid amplifiers and, in some cases, those which use bipolar input op amps.The AD845 is ideal for use in applications such as active filters, high speed integrators, photo diode preamps, sample-and-hold amplifiers, log amplifiers, and in buffering A/D and D/A converters. The 250 µV max input offset voltage makes offset nulling unnecessary in many applications. The common-mode rejection ratio of 110 dB over a ±10 V input voltage range represents exceptional performance for a JFET input high speed op amp. This, together with a minimum open-loop gain of 250 V/mV ensures that 12-bit performance is achieved, even in unity-gain buffer circuits.The AD845 conforms to the standard op amp pinout except that offset nulling is to V+. The AD845J and AD845K grade devices are available specified to operate over the commercial 0°C to +70°C temperature range. AD845A and AD845B devices are specified for operation over the -40°C to +85°C industrial temperature range. The AD845S is specified to operate over the full military temperature range of -55°C to +125°C. Both the industrial and military versions are available in 8-pin cerdip packages. The commercial version is available in an 8-pin plastic mini-DIP and 16-pin SOIC; 'J' and 'S' grade chips are also available.

The AD848 and AD849 are high speed, low power monolithic operational amplifiers. The AD848 is internally compensated so that it is stable for closed loop gains of 5 or greater. The AD849 is fully decompensated and is stable at gains greater than 24. The AD848 and AD849 achieve their combination of fast ac and good dc performance by utilizing Analog Devices' junction isolated complementary bipolar (CB) process. This process enables these op amps to achieve their high speed while only requiring 4.8 mA of current from the power supplies.The AD848 and AD849 are members of Analog Devices' family of high speed op amps. This family includes, among others, the AD847 which is unity gain stable, with a gain bandwidth of 50 MHz. For more demanding applications, the AD840, AD841 and AD842 offer even greater precision and greater output current drive.The AD848 and AD849 have good dc performance. When operating with ±5 V supplies, they offer open loop gains of 13 V/mV (AD848 with a 500 Ohm load) and low input offset voltage of 1 mV maximum. Common-mode rejection is a minimum of 92 dB. Output voltage swing is ±3 V even into loads as low as 150 Ohm.

The AD8522 is a complete dual 12-bit, single-supply, voltage output DAC in a 14-pin DIP, or SO-14 surface mount package. Fabricated in a CBCMOS process, features include a serial digital interface, onboard reference, and buffered voltage output. Ideal for +5 V-only systems, this monolithic device offers low cost and ease of use, and requires no external components to realize the full performance of the device.The serial digital interface allows interfacing directly to numerous microcontroller ports, with a simple high speed, three-wire data, clock, and load strobe format. The 16-bit serial word contains the 12-bit data word and DAC select address, which is decoded internally or can be decoded externally using LDA, LDB inputs. A serial data output allows the user to easily daisy-chain multiple devices in conjunction with a chip select input. A reset RS input sets the outputs to zero scale or midscale, as determined by the input MSB.The output 4.095 V full scale is laser trimmed to maintain accuracy over the operating temperature range of the device, and gives the user an easy-to-use one-millivolt-per-bit resolution. A 2.5 V reference output is also available externally for other data acquisition circuitry, and for ratiometric applications. The output buffers are capable of driving ±5 mA.The AD8522 is available in the 14-pin plastic DIP and low profile 1.5 mm SOIC-14 packages.APPLICATIONS Digitally Controlled Calibration Servo Controls Process Control Equipment Computer Peripherals Portable Instrumentation Cellular Base Stations Voltage Adjustment

LDA and LDB can also be activated independently to immediately update their respective DAC registers. An address input decodes DAC A or DAC B when the chip select CS input is strobed. An asynchronous reset input sets the output to zero scale. The MSB bit can be used to establish a preset to midscale when the reset input is strobed.The AD8582 is available in the 24-pin plastic DIP and the surface mount SOIC-24.

The AD8610 (single) and AD8620 (dual) are very high precision JFET input amplifiers featuring ultralow offset voltage and drift, very low input voltage and current noise, very low input bias current, and wide bandwidth. Unlike many JFET amplifiers, the AD8610 input bias current is low over the entire operating temperature range.

The 12-channel AD8802 / AD8804 provides independent digitally-controllable voltage outputs in a compact 20-lead package. This potentiometer divider TrimDAC® allows replacement of the mechanical trimmer function in new designs. The AD8802 / AD8804 is ideal for dc voltage adjustment applications.Easily programmed by serial interfaced microcontroller ports, the AD8802 with its midscale preset is ideal for potentiometer replacement where adjustments start at a nominal value. Applications such as gain control of video amplifiers, voltage controlled frequencies and bandwidths in video equipment, geometric correction and automatic adjustment in CRT computer graphic displays are a few of the many applications ideally suited for these parts. The AD8804 provides independent control of both the top and bottom end of the potentiometer divider allowing a separate zero-scale voltage setting determined by the VREFL pin. This is helpful for maximizing the resolution of devices with a limited allowable voltage control range.Internally the AD8802/AD8804 contains 12 voltage-output digital-to-analog converters, sharing a common reference-voltage input.Each DAC has its own DAC latch that holds its output state. These DAC latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial input digital interface. The serial-data-input word is decoded where the first 4 bits determine the address of the DAC latches to be loaded with the last 8 bits of data. The AD8802/ AD8804 consumes only 10 µA from 5 V power supplies. In addition, in shutdown mode reference input current consumption is also reduced to 10 µA while saving the DAC latch settings for use after return to normal operation.The AD8802 / AD8804 is available in the 20-pin plastic DIP, the SOIC-20 surface mount package, and the 1 mm thin TSSOP-20 package.APPLICATIONS Automatic Adjustment Trimmer Replacement Video and Audio Equipment Gain and Offset Adjustment Portable and Battery Operated Equipment
