Overview
The LTC2192IUKG#PBF is a 2-channel, simultaneous sampling 16-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 and other high-performance applications. It features low power consumption, high signal-to-noise ratio (SNR), and spurious free dynamic range (SFDR), along with ultra-low jitter, which allows for excellent noise performance even when undersampling IF frequencies.
