Overview
The LTC2282CUP from Analog Devices Inc. is a high-performance, dual-channel, 12-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC operates at a sampling rate of 105 Msps and is optimized for low power consumption, making it suitable for demanding applications in imaging and communications.
The device features a single 3V supply, which enables low power operation, and a separate output supply that allows the outputs to drive logic levels from 0.5V to 3.6V. The LTC2282CUP is housed in a compact 64-pin QFN package, enhancing thermal performance and reducing space requirements in system designs.
