Overview
The ADAS3022BCPZ is a 16-bit, 1 MSPS (mega samples per second) successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This device is part of a complete data acquisition system, integrating multiple components to simplify design challenges in various applications. It is built on Analog Devices' proprietary iCMOS high voltage industrial process technology, ensuring high performance and reliability.
The ADAS3022BCPZ features an 8-channel, low leakage multiplexer, a high impedance programmable gain instrumentation amplifier (PGIA) stage, a precision 4.096 V reference and buffer, and a 16-bit SAR ADC. This combination allows for the resolution of eight single-ended inputs or four fully differential inputs up to ±24.576 V when using ±15 V supplies.
