Overview
The LTC2264CUJ-12 is a 2-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This component is optimized for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features exceptional AC performance, including a signal-to-noise ratio (SNR) of 71 dB and a spurious free dynamic range (SFDR) of 90 dB. The ultralow jitter of 0.15 psRMS enables undersampling of IF frequencies with excellent noise performance.
