Working Principle

The TSOP38456 is an active optical receiver that is used for detecting modulated infrared light signals. It is made up of an infrared-sensitive monolith, which is connected to an amplifier circuit. The monolith is composed of a photodiode, which is sensitive to infrared waves, as well as an amplifier integrated circuit and converter circuit.

When infrared light waves are emitted by an IR remote control, they are detected and converted into electricity by the photodiode. The amplifier IC then amplifies the converted signal and outputs it to the converter circuit. This circuit then converts the amplified signal into a digital signal that can be used by a microcontroller or any other digital device.

The TSOP38456 has a wide operational range, with an operating voltage of 2.7-5.5V and a range of -40°C to +85°C. It has a high IR-rejection ratio of 56dB and a wide receiver bandwidth of 10MHz, making it suitable for a variety of applications.
