Overview
The LTC2170IUKG-14 is a 4-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for digitizing high frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 73.7dB and a spurious free dynamic range (SFDR) of 90dB. The ADC also boasts an ultralow jitter of 0.15ps RMS, enabling the undersampling of IF frequencies with excellent noise performance.
