Overview
The AD9266BCPZ-80 is a high-performance, single-channel 16-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 that can 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 16-bit accuracy at sample rates up to 80 MSPS. The device is packaged in a 32-lead RoHS-compliant LFCSP and is specified over the industrial temperature range (−40°C to +85°C).
