Overview
The LTC2263CUJ-12 is a 2-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This component is part of the LTC2263 family and is optimized for digitizing high frequency, wide dynamic range signals. It is particularly suited for demanding communications applications due to its excellent AC performance, including a signal-to-noise ratio (SNR) of 71dB and a spurious free dynamic range (SFDR) of 90dB. The ultralow jitter of 0.15ps RMS allows for the undersampling of IF frequencies with excellent noise performance.
