Optical Receiver Circuit

The LTC6752, along with a high speed high performance FET input operational amplifier like the LTC6268, can be used to implement an optical receiver as shown above. The figure shows the output of the LTC6268 driving the –IN pin of the LTC6752-2, the +IN pin of the LTC6752-2, and the LTC6752 output. The photodiode is being driven by a light source of sinusoidally varying intensity.
