Optical Sensors - Photo Detectors - Remote Receiver

TSOP57438TT2 is one of the latest models of remote receivers developed by Vishay. It has both good applicability and great affordability, upgrading the performance of remote control system. The receiver can work at a maximum frequency of 10 Hz and has an optimized output Waveform for high-performance compared to previous remote receivers.

As a type of photo detector, TSOP57438TT2 features a miniaturize package, low power consumption, high resolution and response time. It provides great IR response rate to form an excellent remote control system. The package includes a photodiode, band-pass filter, amplifier and pulse shaping.

TSOP57438TT2 is generally used in the wireless control systems. The main application field of this receiver is for infrared remote control, where it will receive the IR pulses that are emitting from a remote control. The remote control will send out a code in the IR signals in order to control the electronic device, and thus the receiver should be able to detect it. The TSOP57438TT2 works based on amplitude modulation, which also enables it to detect the difference between the background noise and the code.

The working principle of TSOP57438TT2 begins with the photodiode, which is used to detect the IR pulses that emitted from the remote control. The photodiode will detect the IR light from the remote control and convert it into an electrical pulse. Then the band-pass filter will filter out the weak signals, and the amplifier will convert the electrical signal into a larger signal that can be processed. Finally, the output waveform is optimized so that it can reduce the noise level and detect the difference between the targeted signals and the background noise.

In summary, TSOP57438TT2 is an affordable and applicable remote receiver. It works based on amplitude modulation and provides great IR response rate. With its optimized output Waveform and miniaturize package, TSOP57438TT2 will upgrade the performance of wireless control system tremendously.
