The TDA3047 is designed as one kind of low power consumption infrared remote control receiving circuit that can be used in the TV application. The internal circuit is composed of the controllable high-frequency amplifier (the control range is 66dB), the synchronous demodulator, the reference amplifier, the automatic gain control detector, the input voltage limiter circuit, the pulse shaping circuit and the output buffer. The difference of the TDA3047 and TDA3048 is the polarity of the output signal. This device is in the 16-pin dual-row DIP plastic package.
