| TDA8160 INFRARED REMOTE CONTROL RECEIVER . . . . . . . LOW SUPPLY VOLTAGE (VS = 5V) LOW CURRENT CONSUMPTION (IS = 6mA) INTERNAL 5.5 V SHUNT REGULATOR PHOTODIODE DIRECTLY COUPLED WITH THE I.C. INPUT STAGE WITH GOOD REJECTION AT LOW FREQUENCY LARGE INPUT DYNAMIC RANGE FEW EXTERNAL COMPONENTS 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).

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. 2/4 TDA8160 Figure 1 : Recommended Application Circuit for the Drive of the IC M491 by Means of a Flash Mode IR.
