Unit DAC2
SKU:U012-B
Description
Unit DAC2 is an I2C digital-to-analog signal conversion unit. It uses the GP8413 solution, which can linearly convert 15-bit digital signals into two independent 0-5V/0-10V analog voltages with an output voltage error of 0.2% and a linearity of 0.01%. In terms of expandability, the circuit design allows for the selection of three hardware addresses A2/A1/A0, supporting the simultaneous operation of up to 8 devices with 16 channels output. In terms of safety, the device has a short-circuit protection function, automatically entering protection mode and stopping output when the output pins are shorted to ground. It is suitable for general signal conversion, motor speed control, LED dimming, inverters, power supplies, and industrial analog signal isolation.
