Overview
The LTC2222IUK-11 is a high-performance, 11-bit, 105Msps analog-to-digital converter (ADC) designed by Analog Devices Inc. This ADC is optimized for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 65.4dB and a spurious free dynamic range (SFDR) of 80dB for signals up to 150MHz. The ultralow jitter of 0.15psRMS enables undersampling of IF frequencies with excellent noise performance.
