Overview
The AD9204BCPZ-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 with a multistage differential pipeline architecture and output error correction logic, ensuring 10-bit accuracy at data rates up to 80 MSPS and guaranteeing no missing codes over the full operating temperature range of −40°C to +85°C.
