TSOP2340 Application Field and Working Principle
Optical Sensors – Photo Detectors – Remote Receiver
The TSOP2340 is a high performance remote receiver with a wide business field. It is widely used for infrared switching applications such as televisions, cable boxes, radio players, game consoles, DVD players, and Blu-ray players. The receiver consists of an infrared (IR) sensitive photodiode and a signal pre-amplifier integrated together in one package.The primary application field of TSOP2340 is for consumer and commercial infrared remote control applications. It is able to detect IR signals at frequencies of 36kHz, 38kHz, or 57kHz. It features a very high sensitivity, a wide range of supply voltages and high reliability, making it an ideal choice for infrared remote control solutions.Working Principle
The TSOP2340 consists of two main functional parts, a photodiode and a pre-amplifier. The photodiode is used to capture and receive IR signals emitted from an IR transmitter. The signal pre-amplifier is used to amplify the IR signal, and boost it to a level suitable for the microcontroller’s input.The photodiode is a PIN diode, which takes the form of two metal layers sandwiched between each other, and an IR sensitive substrate material. When exposed to infrared, the photodiode captures the signal which induces an electrical current in the PIN diode. This current is then amplified by the internal pre-amplifier.The pre-amplifier consists of two Boosters – B1 and B2 – which are used to pre-amplify and stabilise the signal. When the photodiode detects an IR signal, the pre-amplifier boosts the signal to a logic threshold level. This signal is then sent to a microcontroller, which takes a corresponding action based on the signal it receives.The output pin of the pre-amplifier can be interfaced directly to a microcontroller through an external pull-up resistor. The internal gain of the pre-amplifier helps to maintain reliable performance over an extended range of supply voltages.Conclusion
The TSOP2340 is an IR sensitive device used for infrared remote control applications. It consists of a photodiode and a pre-amplifier integrated together in one package. The photodiode is used to capture and receive IR signals, while the pre-amplifier is used to amplify the signal and boost it to a level suitable for the microcontroller’s input.The TSOP2340 features a very high sensitivity, a wide range of supply voltages and high reliability, making it an ideal choice for infrared remote control solutions.The specific data is subject to PDF, and the above content is for reference
