Overview
The AD9649BCPZRL7-65 is a high-performance, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic, single-channel 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. The device is designed with a multistage differential pipeline architecture and includes output error correction logic to ensure 14-bit accuracy at sampling rates up to 65 MSPS. It also includes an on-chip voltage reference and sample-and-hold circuit, making it suitable for a wide range of high-speed data acquisition applications.
