Overview
The LTC2173IUKG-14 is a 4-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This component is optimized for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features low power consumption, high signal-to-noise ratio (SNR), and spurious free dynamic range (SFDR), along with ultralow jitter, which allows for excellent noise performance even when undersampling IF frequencies.
