The CX20106/CX20106A is designed as the infrared remote control receiving preamplifier bipolarity circuit that can be used in the TV application. The internal circuit is composed of the preamplifier, the ABLC, the amplitude limiting amplifier，the bandpass filter, the peak value wave detector and the waveform shaping circuit. The CX20106A is the improved model of CX20106, the difference between the CX20106 and CX20106A is the electrical parameter. Features Low power voltage, the typical value is 5V.Low power consumption. When Vcc=5V, the typical power consumption is 9mW.You can change the centre frequency of the bandpass filter by changing the resistance between the pin-5 and the power supply.It can be connected with the PIN photoelectric diode. It is in the 8-pin single row DIP plastic package.The matching model is M50462AP.
