Hat DAC2
SKU:U068-B
Description
Hat DAC2 is an I2C digital-to-analog signal conversion unit designed for the StickC series controllers. Using the GP8413 solution, this chip can linearly convert a 15-bit digital quantity into two independent 0–5V / 0–10V analog voltages with an output voltage error of 0.2% and linearity of 0.01%. For scalability, the circuit design allows selection via three hardware address pins (A2/A1/A0). In terms of safety, the device supports output short-circuit protection — when the output pin is shorted to ground, it automatically enters protection mode and stops output. It is suitable for general signal conversion, motor speed control, LED dimming, inverters, power supplies, and industrial analog signal isolation applications.

Address Selection
By setting pins A0, A1, and A2 to high (1) or low (0), you can obtain eight different I2C addresses from 0x58 to 0x5F. Connecting a resistor indicates a high level (1), while leaving it unconnected means a low level (0).
