Overview
The ADAS3022BSTZ is a 16-bit, 1 MSPS (mega samples per second) successive approximation register (SAR) analog-to-digital converter (ADC) and data acquisition system produced by Analog Devices Inc. This device is manufactured using Analog Devices' proprietary iCMOS high voltage industrial process technology. It integrates 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 charge redistribution ADC. The ADAS3022 simplifies design challenges by eliminating the need for signal buffering, level shifting, amplification/attenuation, common-mode rejection, and settling time, thereby enabling a smaller form factor, faster time to market, and lower cost.
