CIRCUIT DESCRIPTION (see the block diagram)

The infrared light received from D1 generates an

AC signal that comes in to the device at pin 5. The

capacitor C1 and the integrated 10kΩ resistor

(pin 4) filter out the low frequency noise.

TEST CIRCUIT

The first stage shows a voltage gain of about 28dB ;

the second stage is a voltage to current converter

of 50mA/V (R2 = Zero). A sensitive peak detector

detects the amplifier signal ; one open collector

output (pin 1) gives out the recovered pulses.
