Overview
The LTC2240-10, produced by Analog Devices Inc., is a high-performance 10-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC operates at a sampling rate of 170 million samples per second (Msps) and is ideal for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 60.6 dB and a spurious free dynamic range (SFDR) of 80 dB. The ultralow jitter of 95 fs RMS enables IF undersampling with excellent noise performance.
