Optical Sensors – Photo Detectors – Remote Receiver

TSOP53256 is an infrared remote receiver specifically designed to receive signals from standard IR remote controls. It is a miniaturized receiver module designed for infrared remote control and infrared data transmission applications. It consists of some of the most advanced IR receiver technology, superior noise-immunity, digital output, and a built-in Atmel microcontroller for efficient signal processing.

Application Field

The TSOP53256 is suitable for a wide range of applications such as remote control units for TVs, VCRs, Hi- Fi equipment, STBs, air conditioners, and other consumer products. It is commonly used in TV controllers and home theater systems, allowing users to control their source device from a remote distance. Other applications include projectors, motorized gates, shutters, light intensity control, air conditioners, home appliances, computerized toys, robotic systems, and security& surveillance systems.

Working Principle

The TSOP53256 works by receiving and processing an infrared signal, which is emitted as an invisible beam of light from the remote control’s transmitter. The receiver is connected to the electronic device to be controlled, and contains a low noise amplifier, a band-pass filter, a demodulator, and a microcontroller. When the TSOP53256 receives a signal from the remote control, it amplifies it, filters it, and finally demodulates it. The demodulated signal is then sent to the microcontroller for further processing and analysis, and the command is sent to the device it is connected to.

The TSOP53256 is a versatile and reliable remote receiver thanks to its robustness to environmental noises, low power requirements, and its versatility in sensing a wide range of frequencies and modulation types. It is also relatively inexpensive and can easily be integrated into a variety of products.
