Hat DAC2
SKU:U068-B
Description
Hat DAC2 is a dual-channel digital-to-analog converter for StickC series controllers built around the 15-bit GP8413 DAC. It receives digital values over I2C and provides two independent analog voltage outputs. Each channel supports a DC 0 ~ 5V or DC 0 ~ 10V output range. 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 outputs applications.

| 0 | 0 | 0 | 0x58 |
| 0 | 0 | 1 | 0x59 (Default) |
| 0 | 1 | 0 | 0x5A |

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).
