Overview
The LTC2207IUK, produced by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed for digitizing high-frequency, wide dynamic range signals. This ADC operates at a sampling rate of 105 Msps and is particularly suited for demanding communications applications. It features a single 3.3V supply, low power dissipation, and excellent AC performance, including a 78.2 dB noise floor and 100 dB spurious free dynamic range (SFDR). The ultralow jitter of 80 fs RMS enables the undersampling of high input frequencies with excellent noise performance.
