This document introduces the features and characteristics of LTC2288/LTC2287/LTC2286, these three 10-bit, 65/40/25Msps, low noise 3V ADCs.
The LTC2288, LTC2287 and LTC2286 are dual 10‑bit analog‑to‑digital converters offering sample rates of 65 Msps, 40 Msps and 25 Msps respectively. They operate from a single 3 V supply (2.7 V – 3.4 V) and provide low‑noise performance suitable for imaging, communications and instrumentation applications.
The document provides absolute maximum ratings, electrical characteristics, typical performance graphs, package dimensions and a list of related parts. It also details analog input ranges, digital I/O specifications, power consumption and internal reference parameters.
