Overview
The LTC2294CUP, produced by Analog Devices Inc., is a dual 12-bit analog-to-digital converter (ADC) designed for high-frequency, wide dynamic range signal digitization. This component operates at a sample rate of 80 Msps and is powered by a single 3V supply, making it suitable for low-power applications. The LTC2294CUP is particularly adept at handling demanding imaging and communications tasks due to its excellent AC performance, which includes a signal-to-noise ratio (SNR) of 70.6 dB and a spurious free dynamic range (SFDR) of 90 dB at 70 MHz input frequencies.
