Overview
The AD9204BCPZRL7-80 is a high-performance, dual-channel, 10-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 using a multistage differential pipeline architecture with output error correction logic, ensuring 10-bit accuracy at high data rates and guaranteeing no missing codes over the full operating temperature range.
