Overview
The LTC2260IUJ-14 is a high-performance, 14-bit analog-to-digital converter (ADC) designed by Analog Devices Inc. This ultra-low power ADC is optimized for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications and other high-speed applications. With a sampling rate of 105 MS/s, it offers excellent AC performance, including a signal-to-noise ratio (SNR) of 73.4 dB and a spurious free dynamic range (SFDR) of 85 dB. The device features ultralow jitter of 0.17 ps RMS, enabling the undersampling of IF frequencies with excellent noise performance.
