The input range of the ADC can be optimized with the PGA front end. The LTC2207/LTC2206 are perfect for demanding communications applications, with AC performance that includes 78.2dB Noise Floor and 100dB spurious free dynamic range (SFDR). Ultralow jitter of 80fsRMS allows undersampling of high input frequencies with excellent noise performance. Maximum DC specs include ±4LSB INL, ±1LSB DNL (no missing codes) over temperature.
