DIP8 (Plastic Package) ORDER CODE : TDA 8160
PIN CONNECTIONS 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). BLOCK DIAGRAM

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. 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.
