Overview
The LTC2170CUKG-14#TRPBF is a 14-bit, low-power, quad analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the LTC2170-14 series and is designed for digitizing high-frequency, wide dynamic range signals. It is particularly suited for demanding communications applications due to its excellent AC performance, which includes a signal-to-noise ratio (SNR) of 73.7dB and a spurious free dynamic range (SFDR) of 90dB. The ADC features ultralow jitter of 0.15psRMS, enabling the undersampling of IF frequencies with excellent noise performance.
