Overview
The LTC2164CUK, produced by Analog Devices Inc., is a 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 offers high AC performance, including a signal-to-noise ratio (SNR) of 76.8dB and a spurious free dynamic range (SFDR) of 90dB. The ultralow jitter of 0.07ps RMS enables undersampling of IF frequencies with excellent noise performance.
