Overview
The LTC2263IUJ-14, produced by Analog Devices Inc., is a 2-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) designed for digitizing high frequency, wide dynamic range signals. This device is particularly suited for demanding communications applications, offering exceptional AC performance with a signal-to-noise ratio (SNR) of 73.7dB and a spurious free dynamic range (SFDR) of 90dB. The ultralow jitter of 0.15ps RMS enables undersampling of IF frequencies with excellent noise performance, making it ideal for applications requiring high accuracy and low noise.
