Overview
The AD9231BCPZ-80 is a high-performance, dual-channel, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic ADC operates from a single 1.8 V analog power supply and features a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families. It is designed with a multistage differential pipeline architecture and includes output error correction logic to ensure 12-bit accuracy at data rates of up to 80 MSPS. The device also includes a high-performance sample-and-hold circuit and an on-chip voltage reference, making it suitable for a variety of high-speed applications.
