Overview
The LTC2159CUK#TRPBF is a high-performance, 16-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This sampling ADC is optimized for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications and other high-speed applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 77dB 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.
