The TSOP4136 is a 36kHz Miniaturized Receiver Module for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame. The demodulated output signal can be directly connected to a microprocessor for decoding. The receiver module is immune to dimmed LCD backlighting and any fluorescent lamps. AGC3 and AGC5 may also suppress some data signals in case of continuous transmission.
