CIRCUIT DESCRIPTION (see the blockdiagram)
The infrared light received from D1 generatesan signal that comesinto the deviceat pin5. The
capacitor C1 and the integrated 10kΩ resistor
(pin4) filter out the low frequencynoise.
The first stage showsa voltagegainofabout28dB;
the second stageisa voltageto current converter 50mA/V (R2= Zero).A sensitive peak detector
detects the amplifier signal; one open collector
output (pin1) gives out the recovered pulses.
