IR Receivers: Understanding the AGC Function and Mapping Tool

One of the unique features that makes Vishay's IR Receivers the best at filtering out optical noise is the AGC function. This video explains the feature, how to use the mapping tool on the Vishay website, and where in the datasheet AGC is shown.

Nice Video 🥺

which AGC would be best for IR transmission in long rage sunlight applications? I get varying results from any sensor I try and never really found a pattern.

@@dmitrysnegiryov yes, I've always wondered if it was necessary. We just send 2500uS pulse, wait 500uS, then data begins. Some datasheet say we need a very long wait period after the header/calibration pulse, but it seems to work fine w/o it too. It seems AGC 1/2 worked best for us, and higher AGC made it less receptive outdoors.

Please suggest part number
I need to recive continues pulses at reciver
transmitter transmit pulses as below
7 pulses of 38hz
pause 300us
7 pulse of 38kz
Pause 300us
Above sequence continuously transmit by transmitter
