DESCRIPTION
The TDA8160 is a monolithic integrated circuit
in-lead minidip plastic package specially designed
to amplify the infrared signals in remote 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 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 10k
resistor
(pin 4) filter out the low frequency noise.
The first stage shows a voltage gain of about 28dB ;
the second stage is a voltage to current converter
of 50mA/V (R
2
= Zero). A sensitive peak detector
detects the amplifier signal ; one open collector
output (pin 1) gives out the recovered pulses.
