AD9625BBPZRL-2.6

Analog To Digital Converters (ADC) Overview

The AD9625BBPZRL-2.6 is a 12-bit monolithic sampling analog-to-digital converter (ADC) operating at conversion rates up to 2.6 GSPS. It features a differential analog input with a 1.2 V p-p range and a 3.2 GHz full-power analog input bandwidth, designed for sampling wideband signals up to the second Nyquist zone. The device utilizes a pipelined architecture with integrated output error correction logic. Digital data is transmitted via a high-speed JESD204B serial interface, configurable in one-, two-, four-, six-, or eight-lane modes, supporting link speeds up to 6.5 Gbps at maximum sampling. Power supplies include 1.3 V and 2.5 V rails, with an internal reference voltage of 1.2 V.
