What the GP8403 family does
The GP8403 is a 12-bit dual-channel digital-to-analog converter that accepts I2C control to generate two independent 0-5V or 0-10V analog outputs. It operates with a 9V to 36V supply, features a typical 0.2% output voltage error, and includes built-in short-circuit protection. The device supports up to eight units on a single bus via hardware address selection. Engineers typically use this component for general signal conversion, motor speed control, LED dimming, and industrial analog signal isolation. It functions across an industrial temperature range of -40°C to 85°C with a typical power consumption of 2mA.
