GP1UM287RK is an optical detector consisting of a photodiode and a transimpedance amplifier that integrated on a single monolithic chip. This device can directly detect infrared or visible light radiation which is then transformed into current. It is most commonly used in remote controlled proximity sensing applications.The working principle of the GP1UM287RK is based on the generation of photo-current in the photodiode. When infrared or visible light radiation falls on the surface of the chip, electrons get excited and are injected into the depletion region of the diode, thereby generating current. The current is then amplified using the transimpedance amplifier. This boosts the current and its performance is further enhanced by adding a guard ring around the photodiode. The GP1UM287RK is used in various applications such as proximity sensing, remote control, Active Infrared (AI), remote receivers, and Light Detecting and Ranging (LIDAR) sensing. Proximity sensing finds use in industrial, medical, and robotic applications. Remote control and AI applications allow for remote operation of various home appliances using infrared light irradiation. In LIDAR sensing, this device is used to detect and measure the distance of an object that reflects or emits light radiation. It is also used to detect and track objects in the fields of autonomous vehicles, robotics, and machine vision.The GP1UM287RK is designed to operate in a wide rage of conditions with high sensitivity and low noise. It is one of the most sensitive detectors in the market which can detect light signals even under weak light conditions. The wide range of operating temperatures, makes it ideal for applications subjected to extreme temperatures. It can also operate in high pressure environments such as automotive or industrial environments.GP1UM287RK has a fast response time which is less than 10 µs and is therefore suitable for applications requiring fast response time. This device also uses low power operation, enabling it to reduce the overall power consumption in the application.In summary, the GP1UM287RK is an optical detector that utilizes a photodiode and transimpedance amplifier to convert light radiation into current. This device is suitable for use in proximity sensing, remote control, AI, remote receivers, and LIDAR sensing, among others. It is designed to operate under extreme environmental conditions and can operate at low power consumption with fast response time of up to 10 µs.
