Overview
The AD9629BCPZRL7-65, produced by Analog Devices Inc., is a high-performance, 12-bit, single-channel analog-to-digital converter (ADC). It operates from a single 1.8 V analog power supply and features a separate digital output driver supply that can accommodate 1.8 V to 3.3 V logic families. This ADC is designed using a multistage differential pipeline architecture with output error correction logic, ensuring 12-bit accuracy at sampling rates up to 80 MSPS and guaranteeing no missing codes over the full operating temperature range of −40°C to +85°C.
