Overview
The LTC2264IUJ-12 is a 2-channel, simultaneous sampling 12-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 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 enables excellent noise performance even when undersampling IF frequencies.
