This document describes the features and characteristics of the 16-Bit, 125 MSPS/105 MSPS/80 MSPS, 1.8 V Analog-to-Digital Converter AD9265 Rev. A.
The AD9265 is a 16‑bit, 125 MSPS analog‑to‑digital converter designed for communications, software‑defined radio and broadband data applications. It features a differential pipelined architecture, on‑chip dither, programmable voltage reference, and supports both 1.8 V CMOS and LVDS output modes.
The device operates from a single 1.8 V supply, offers power‑down and standby modes for energy saving, and provides a standard 3‑wire SPI interface for configuration. It is available in a 48‑lead LFCSP package and is rated for industrial temperature range (‑40 °C to +85 °C).
