Overview
The LTC2260CUJ-12 is a 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This device is part of the LTC2261-12/LTC2260-12/LTC2259-12 family, which are sampling ADCs optimized for digitizing high-frequency, wide dynamic range signals. These converters are particularly suited for demanding communications applications, offering excellent AC performance with a signal-to-noise ratio (SNR) of 70.8dB and a spurious free dynamic range (SFDR) of 85dB. The ultralow jitter of 0.17ps RMS enables undersampling of IF frequencies with superior noise performance.
