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