Part Number: AFE4405 According to the datasheet, the performance of both the receiver and the transmitter should be about 100dBFS. Thus, I would expect to measure a voltage noise level in the range of 20uV, when settings according to the datasheet is used. However, I measure a much higher noise value. I use the evaluation board and the attached LED/photodiode board. I get about 1.64 mV(RMS) even if I set the LED current to zero. Why??
