DESCRIPTION
The TDA8160 is a monolithic integrated circuit
in-leadminidipplastic package speciallydesigned
to amplifythe infrared signals inremote controlled
TV, Radio or VCR sets. It can be used in flash
transmission mode in conjunction with dedicated
remote control circuits (for example : M491-494).

CIRCUIT DESCRIPTION(see the blockdiagram)
The infrared light received from D1 generates an
AC signalthatcomes into the deviceat pin5. The
capacitor C1 and the integrated 10kΩ resistor
(pin 4) filterout the low frequency noise.
TEST CIRCUIT
