Overview
The LTC2174CUKG-14, manufactured by Analog Devices Inc., is a 4-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC). This device is designed for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features high AC performance, including a signal-to-noise ratio (SNR) of 73.1dB and a spurious free dynamic range (SFDR) of 88dB. The ADC also boasts ultralow jitter of 0.15ps RMS, enabling the undersampling of IF frequencies with excellent noise performance.
