Optical sensors are widely used in many applications for measuring or detecting physical parameters in fields such as biology, medical science, robotics, and industrial automation. Among them, photo detectors or remote receivers are mainly used to convert optical signals to electrical signals. In this article, we will discuss the application field and working principle of TSOP75256TR, a type of photo detector.TSOP75256TR is a fully integrated optical receiver with a wide, adjustable working angle/distance range, which are from 0-15° respectively from 1-5cm. It is used in various optical data transmission and control systems, including home alarm systems, interactive TV systems, remote control systems, industrial controls, and automotive controls.The TSOP75256TR is typically composed of four major components. The first is an infrared emitting diode (IRED) that is used to provide a constant source of light. The second is a lens system that receives and collimates the light and directs it towards the detector. The third consists of the detector itself, which consists of a PIN photodiode and a transimpedance amplifier (TIA). The fourth is a bandpass filter that selects the desired frequency band for detection.When a remote control signal is transmitted, the IRED emits a short burst of infrared pulses of a specific frequency. This light is then collimated and directed towards the photo detector, where it causes a current flow through a PIN photodiode. The TIA amplifies this current signal which is then filtered by the bandpass filter and sent to the output pin.The TSOP75256TR has a number of advanced features, which make it suited for use in many different applications. It has a low start-up current, a high sensitivity, a low supply voltage, a wide dynamic range, and a wide operating angle/distance range.In conclusion, the TSOP75256TR is a versatile photo detector that is used in a wide variety of optical data transmission and control systems. It features a wide, adjustable working angle/distance range, a low start-up current, a high sensitivity, a low supply voltage, and a wide dynamic range. As such, it is used for a wide range of applications including home alarm systems, interactive TV systems, remote control systems, industrial controls, and automotive controls.
