The AD974 is a four-channel, 16-bit, 200 kSPS data acquisition system with a serial interface. The part contains an input multiplexer, a high-speed 16-bit sampling ADC and a +2.5 V reference. All of this operates from a single +5 V power supply that has low power-down modes and external or internal reference voltage selection.

This document mainly introduces the calibration registers of AD7739, including two register sets. The first register set includes 24-bit offset register and 24-bit gain register, which affect all channels. The second register set includes per channel 24-bit offset register and a 24-bit per channel gain register, which affect a specific channel only.

The document describes the Analog Devices' variable resolution monolithic resolver-to-digital converters AD2S81A/AD2S82A. The product features a one-chip solution, user-settable resolution, ratiometric tracking conversion, and user-determined dynamic performance.

The AD9050 is an 10-bit monolithic sampling analog-to-digital converter (ADC) with an onboard track-and-hold and reference from Analog Devices. It is designed for low cost, high performance applications and requires only +5 V and an encode clock to achieve 40 MSPS or 60 MSPS sample rates with 10-bit resolution.

AD9012 is an 8-bit, ultrahigh speed analog-to-digital converter produced by Analog Devices. The device has a maximum sampling rate of 100MSPS and features low input capacitance and low power consumption. It is suitable for applications such as radar guidance, digital oscilloscopes/ATE equipment, laser/radar warning receivers, digital radio, electronic warfare (ECM, ECCM, ESM) and communication/signal intelligence.

The AD1380 is a complete, low cost 16-bit analog-to-digital converter, including internal reference, clock and sample/hold circuitry. It features 50kHz throughput and ±1/2 LSB nonlinearity. The AD1380 is packaged in a 32-lead hermetic DIP and provides parallel output.

AD1870 is a single-supply 5V 16-bit stereo ADC with single-ended dual-channel analog inputs, 92dB (typical) dynamic range, 0.006dB decimator pass-band ripple, fourth order 64x oversampling, 256 or 384x input clock, flexible serial output interface, etc.

This document introduces the use of AD7877 touch screen controller and Intel PXA250 processor under Windows CE.NET, including connection method and driver development

The AD9870 is a low-power, high-performance, programmable single-chip RF receiver that converts 10 MHz to 300 MHz of RF input signal to baseband (I/Q) digital output. The AD9870 features 12 dB SSB NF, > –1 dBm IIP3 and 25 dB continuous AGC range, and supports LO and sampling clock synthesis.

This document lists the known bugs, anomalies, and workarounds for the ADT7411

The AD7877 is a 12-bit successive approximation ADC with a synchronous serial interface and low on resistance switches for driving touch screens. The AD7877 features direct battery measurement on two inputs, temperature and touch-pressure measurement. The AD7877 has many user-programmable conversion controls, which include variable acquisition time, first conversion delay, and averaging. It is ideal for battery-powered systems such as personal digital assistants, smart phones, and other portable equipment with resistive touch screens. One of the AD7877’s key features is the STOPACQ input pin, which can be used to reduce the effects of noise on the touch screen measurements. This application note explains in detail how noise can affect the touch screen measurements, where this noise comes from, and how to use the AD7877’s STOPACQ feature to reduce or eliminate this noise in an application.

The AD10678 is a 16-bit, 80 MSPS high-performance analog-to-digital converter (ADC) for applications that demand increased SNR levels. Exceptional noise performance and a typical signal-to-noise ratio of 80 dBFS are obtained by digitally postprocessing the outputs of four ADCs. A single analog input and PECL sampling clock and 3.3V and 5V power supplies are required.

The document describes the features and characteristics of the AD7868 LC2MOS complete 12-bit analog I/O system, including a 12-bit ADC and 12-bit DAC. It has a throughput rate of 83 kHz and a signal-to-noise ratio of 72 dB. The system can be used in various applications such as digital signal processing, speech recognition and synthesis, spectrum analysis, high-speed modems, and DSP servo control.
