Overview
The LTC2208CUP#TRPBF, 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 sample rate of 130 Msps and is particularly suited for demanding communications applications. It features a programmable gain amplifier (PGA) front end, allowing for input ranges of 2.25V p-p or 1.5V p-p, and boasts excellent AC performance with a 78 dBFS noise floor and 100 dB spurious free dynamic range (SFDR). The ultra-low jitter of 70 fs RMS enables undersampling of high input frequencies with excellent noise performance.
