I found some different from datasheet When testing AFE4490EVM. On page 88, The full-scale output of the transimpedance amplifier is ±1 V and the full-scale input to the ADC is ±1.2 V. However, I tested the voltage of RXOUTP & RXOUTN can reach about 1.7V (RF=10kΩ, GAIN=1). Is this result correct? Can I use TIA output 1.7V? And how to improve the SNR value? Thanks a lot!
