Overview
The LTC2163IUK, manufactured by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC is part of the LTC2165/LTC2164/LTC2163 family and is particularly suited for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 76.8 dB and a spurious free dynamic range (SFDR) of 90 dB. The ultralow jitter of 0.07 ps RMS enables undersampling of IF frequencies with superior noise performance.
