Hat DAC2

SKU:U068-B

Description

Hat DAC2 is an I2C digital-to-analog signal conversion unit compatible with the StickC series hosts. It uses the GP8413 solution, and in terms of precision, 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 up to 0.01%. In terms of expandability, the circuit design allows selection through a three-bit hardware address A2/A1/A0. In terms of safety performance, the device supports output short-circuit protection, automatically entering protection mode to stop output when the output pin is shorted to ground. It is suitable for general signal conversion, motor speed control, LED dimming, inverters, power supplies, and industrial analog signal isolation.

Address Selection

By setting the A0, A1, A2 pins to high (1) or low (0), you can obtain 8 different I2C addresses from 0x58 to 0x5F. Connected resistors are considered high (1), while unconnected resistors are low (0).
