Overview
The LTC2249CUH#TRPBF is a 14-bit, 80Msps (mega-samples per second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding applications in imaging and communications. The ADC operates on a single 3V supply, enabling low power consumption, and features a separate output supply that allows the outputs to drive logic levels from 0.5V to 3.6V.
