ADAS3022BCPZ-RL7

Analog To Digital Converters (ADC) Overview

The ADAS3022BCPZ-RL7 is a complete 16-bit, 1 MSPS data acquisition system manufactured on Analog Devices' proprietary iCMOS high voltage process. It integrates an 8-channel low leakage multiplexer, a high impedance programmable gain instrumentation amplifier (PGIA) with >100 dB common-mode rejection, a precision 4.096 V reference, and a 16-bit SAR ADC. The device supports differential input ranges up to ±24.576 V using ±15 V supplies. It features user-programmable input ranges, a channel sequencer with individual gains, and an auxiliary input for direct PulSAR ADC interface. The component utilizes a serial 4-wire SPI-compatible digital interface operating from 1.8 V to 5 V.
