Overview
The AD7657YSTZ-1-RL is a high-performance, multi-channel analog to digital converter (ADC) designed by Analog Devices Inc. This component is part of the AD7657 series, which features six independent 14-bit successive approximation register (SAR) ADCs. It is optimized for data acquisition systems requiring high accuracy and low power consumption.
The AD7657YSTZ-1-RL is built using the iCMOS® process, combining high voltage silicon with submicron CMOS and complementary bipolar technologies. This allows the device to handle bipolar input signals while reducing power consumption and package size.
