Overview
The LTC2241-10, 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 210 Msps, making it ideal for demanding communications applications. It features excellent AC performance, including a signal-to-noise ratio (SNR) of 60.5 dB and a spurious free dynamic range (SFDR) of 78 dB. The ultralow jitter of 95 fsRMS enables IF undersampling with superior noise performance.
