IR Receivers

The fully integrated infrared receiver is a miniaturized component developed for the infrared remote control system. The infrared receiving diode chip and the preamplifier chip are packaged together with epoxy resin. The demodulated output signal can be directly sent to the microprocessor for decoding. Its main advantage is that it can effectively overcome the interference of the surrounding environment. There are two types of packaging: direct plug and patch.

Its characteristics are as follows:

● low power consumption

● ultra miniaturization

● overcome all kinds of light interference

● strong anti-interference ability

● built in PCM frequency filter

● output low level is valid during operation

● wide power supply voltage range: 2.7V ~ 5.5V

● code type adaptability: wide code type adaptability

● TTL and CMOS levels are compatible, and there is no interference pulse output

● carrier frequency: 20kHz, 36 kHz, 38 kHz, 40 kHz, 56 kHz
