This document describes the features and characteristics of the 16-bit, 20 MSPS/40 MSPS/65 MSPS/80 MSPS, 1.8V Analog-to-Digital Converter AD9266, including operating voltage, output supply voltage, signal-to-noise ratio, spurious-free dynamic range, power consumption, input bandwidth, etc.
The AD9266 is a monolithic, single‑channel 16‑bit analog‑to‑digital converter that operates from a 1.8 V analog supply and supports sample rates of 20 MSPS, 40 MSPS, 65 MSPS and 80 MSPS. It offers differential inputs with a 700 MHz analog bandwidth, on‑chip voltage reference, and programmable digital test patterns.
The document details electrical specifications, pin‑out tables, timing diagrams, power‑down modes, and design guidelines for PCB layout and grounding. Application examples include communications, handheld instruments, and medical imaging systems.
