SX8725CWLTDT Working Principle

The SX8725CWLTDT working principle consists of two steps. Firstly, it converts optical energy into electronic energy. It consists of two parts, an optical circuit made of a semiconductor and a detection circuit. The input optical energy could be laser, LED or infrared light energy. The optical energy is converted into electric energy by the semiconductor, which is then input into the detection circuit.

The detection circuit consists of a transimpedance amplifier and a filter circuit. The transimpedance amplifier converts the current signal output by the optical circuit into a voltage signal. The filter circuit processes the voltage signal. Afterwards, the voltage signal is amplified, converted to a digital signal and output by a pin interface.

Secondly, the processor chip processes the digital signal output by the detection circuit and then output the result to the pin interface. The result output by the chip is the laser power, which is expressed by an exponential voltage.
