Overview
The LTC2175CUKG-12 is a 4-channel, simultaneous sampling 12-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 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.
