DC324A

Analog Devices Inc.
The LTC1876 is a high performance triple output switching regulator. It incorporates a dual step-down switching controller that drives all N-channel synchronous power MOSFET stages. A step-up regulator with an internal 1A, 36V switch provides the third output.The step-down controllers minimize power loss and noise by operating the output stage of each controller out of phase. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. A RUN/SS pin for each controller provides both soft-start and an optional timed, short-circuit shutdown that can be configured to latch offone or both controllers. Current foldback provides additional short-circuit protection. In an overvoltage condition, the bottom MOSFET is latched on until VOUT returns to normal. The FCB pin can be used to inhibit Burst Mode operation or to enable regulation of a secondary output voltage.The step-up regulator operates at 1.2MHz, allowing the use of tiny low cost capacitors and inductors. In addition,its internal 1A switch allows high current outputs to be generated. Its current mode control scheme provides excellent line and load regulation.Applications 3.3V Input Step-Down Converter Notebook and Palmtop Computers, PDAs Battery-Operated Digital Devices

The LTC1563-2/LTC1563-3 are a family of extremely easy-to-use, active RC lowpass filters with rail-to-rail inputs and outputs and low DC offset suitable for systems with a resolution of up to 16 bits. The LTC1563-2, with a single resistor value, gives a unity-gain Butterworth response. The LTC1563-3, with a single resistor value, gives a unity-gain Bessel response. The proprietary architecture of these parts allows for a simple resistor calculation:R = 10k (256kHz/fC); fC = Cutoff Frequencywhere fC is the desired cutoff frequency. For many applications,this formula is all that is needed to design a filter.By simply utilizing different valued resistors, gain andother responses are achieved.The LTC1563-X features a low power mode, for the lowerfrequency applications, where the supply current is reducedby an order of magnitude and a near zero powershutdown mode.The LTC1563-Xs are available in the narrow SSOP-16package (Same footprint as an SO-8 package).Applications Discrete RC Active Filters and Modules Antialiasing Filters Smoothing or Reconstruction Filters Linear Phase Filtering for Data Communication Phase Locked Loops

DC342A-A

Analog Devices Inc.
The LTC1911 is a switched capacitor step-down DC/DC converter that produces a 1.5V or 1.8V regulated output from a 2.7V to 5.5V input. The part uses switched capacitor fractional conversion to achieve high efficiency over the entire input range. No inductors are required. Internal circuitry controls the step-down conversion ratio to optimize efficiency as the input voltage and load conditions vary. Typical efficiency is over 25% higher than that of a linear regulator.A unique constant frequency architecture provides a low noise regulated output as well as lower input noise than conventional charge pump regulators. High frequency operation (fOSC = 1.5MHz) simplifies output filtering to further reduce conducted noise. To optimize efficiency,the part enters Burst Mode? operation under light load conditions.Low operating current (180?A with no load, 10?A in shutdown) and low external parts count (two 1?F flying capacitors and two 10?F bypass capacitors) make the LTC1911 ideally suited for space constrained battery powered applications. The part is short-circuit and over temperature protected, and is available in an 8-pin MSOP package.Applications Handheld Computers Cellular Phones Smart Card Readers Portable Electronic Equipment Handheld Medical Instruments Low Power DSP Supplies

Analog Devices Inc.
The AD7887 is a high speed, low power, 12-bit analog-to-digital converter (ADC) that operates from a single 2.7 V to 5.25 V power supply. The AD7887 is capable of 125 kSPS throughput rate. The input track-and-hold acquires a signal in 500 ns and features a single-ended sampling scheme. The output coding for the AD7887 is straight binary, and the part is capable of converting full power signals of up to 2.5 MHz.The AD7887 can be configured for either dual- or single-channel operation via the on-chip control register. There is a default single-channel mode that allows the AD7887 to be operated as a read-only ADC. In single-channel operation, there is one analog input (AIN0) and the AIN1/VREF pin assumes its VREF function. This VREF pin allows the user access to the part?s internal 2.5 V reference, or the VREF pin can be overdriven by an external reference to provide the reference voltage for the part. This external reference voltage has a range of 2.5 V to VDD. The analog input range on AIN0 is 0 to VREF.In dual-channel operation, the AIN1/VREF pin assumes its AIN1 function, providing a second analog input channel. In this case, the reference voltage for the part is provided via the VDD pin. As a result, the input voltage range on both the AIN0 and AIN1 inputs is 0 to VDD.CMOS construction ensures low power dissipation of typically 2 mW for normal operation and 3 ?W in power-down mode. The part is available in an 8-lead, 0.15-inch-wide narrow body SOIC and an 8-lead MSOP package.Product HighlightsSmallest 12-bit dual-/single-channel ADC; 8-lead MSOP package.Lowest power 12-bit dual-/single-channel ADC.Flexible power management options, including automatic power-down after conversion.Read-only ADC capability.Analog input range from 0 V to VREF.Versatile serial input/output port (SPI/QSPI/MICROWIRE/ DSP compatible).ApplicationsBattery-powered systems (personal digital assistants, medical instruments, mobile communications)Instrumentation and control systemsHigh speed modems

The AD7991 /?AD7995?/?AD7999 are 12-/10-/8-bit, low power, successive approximation ADCs with an I2C?-compatible interface. Each part operates from a single 2.7 V to 5.5 V power supply and features a 1 ?s conversion time. The track-and-hold amplifier allows each part to handle input frequencies of up to 14 MHz, and a multiplexer allows taking samples from four channels.Each AD7991 / AD7995 / AD7999 provides a 2-wire serial interface compatible with I2C interfaces. The AD7991 and AD7995 come in two versions and each version has an individual I2C address. This allows two of the same devices to be connected to the same I2C bus. Both versions support standard, fast, and high speed I2C interface modes. The AD7999 comes in one version.The AD7991 / AD7995 / AD7999 normally remain in a shutdown state, powering up only for conversions. The conversion process is controlled by a command mode, during which each I2C read operation initiates a conversion and returns the result over the I2C bus.When four channels are used as analog inputs, the reference for the part is taken from VDD; this allows the widest dynamic input range to the ADC. Therefore, the analog input range to the ADC is 0 V to VDD;. An external reference, applied through the VIN3/VREF input, can also be used with this part.PRODUCT HIGHLIGHTS Four single-ended analog input channels, or three single-ended analog input channels and one reference input channel.
