Overview
The LTC2164IUK is a 16-bit, 105Msps low power 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 high AC performance, including 76.8dB signal-to-noise ratio (SNR) and 90dB spurious free dynamic range (SFDR). The ADC also boasts ultralow jitter of 0.07psRMS, allowing for undersampling of IF frequencies with excellent noise performance.
