Overview
The LTC2208CUP#PBF is a high-performance, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding communications applications. With a sampling rate of 130 Msps and a full power bandwidth of 700 MHz, the LTC2208 offers exceptional AC performance, including a 78 dBFS noise floor and a 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.
