Overview
The AD977CRSZ is a high-speed, low-power 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single 5 V supply and is available in a 28-lead Skinny SSOP package. The AD977 series, including the AD977CRSZ, features a successive approximation, switched capacitor architecture and is factory calibrated to minimize linearity errors. It supports both unipolar and bipolar input ranges, making it versatile for various applications.
