Overview
The ADAS3022BCPZ-RL7, manufactured by Analog Devices Inc., is a comprehensive 16-bit, 1 MSPS (mega samples per second) analog-to-digital data acquisition system. This device is built on Analog Devices' proprietary iCMOS high voltage industrial process technology. It integrates multiple components, including an 8-channel low leakage multiplexer, a high impedance programmable gain instrumentation amplifier (PGIA), a precision 4.096 V reference and buffer, and a 16-bit charge redistribution analog-to-digital converter (ADC) with successive approximation register (SAR) architecture. This integration simplifies design challenges by eliminating the need for external signal buffering, level shifting, amplification/attenuation, and common-mode rejection, thus enabling a smaller form factor, faster time to market, and lower cost.
