Infrared Receiver Circuit

  
The circuit operates from a 5-V supply arid has a current consumption of 2 mA. The output is a current source that drives or suppresses a current of more than 75 with a voltage swing of 4.5 V. The Q-killer circuit eliminates distortion of the output pulses because of the decay of the tuned input circuit at high input voltages.
Infrared Receiver Circuit - schematic

The input circuit is protected against signals of more than 600 mV by an input limiter. The typical input is an AM signal at a frequency of 36 kHz.
