AD9625BBPRL-2.5

Analog To Digital Converters (ADC) Overview

The AD9625BBPRL-2.5 is a 12-bit monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a maximum conversion rate of 2.5 GSPS and features a pipelined architecture with integrated output error correction logic. The device supports differential analog inputs with a 1.2 V p-p range and utilizes a JESD204B high-speed serial interface for data output, configurable in one-, two-, four-, six-, or eight-lane modes. It includes two independent decimate-by-8 or decimate-by-16 filters with 10-bit Numerically Controlled Oscillators (NCOs). Power supplies are 1.3 V and 2.5 V, and it functions within an industrial temperature range of −40°C to +85°C.
