Overview
The LTC2163CUK, produced 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 pipelined ADC is particularly suited for demanding communications applications, offering excellent AC performance with a signal-to-noise ratio (SNR) of 76.8 dB and a spurious free dynamic range (SFDR) of 90 dB. The device features ultralow jitter of 0.07 ps RMS, enabling undersampling of IF frequencies with superior noise performance. It operates with a sampling rate of 80 MS/s and supports both differential and single-ended input modes.
