Hat DAC2

SKU:U068-B

Description

DAC2 Hat is an I2C digital-to-analog signal conversion unit designed to be compatible with the StickC series controllers. It offers high precision and accuracy in its performance by using the GP8413 solution. This chip can linearly convert a 15-bit digital value into two independent analogue voltages of 0-5V or 0-10V. The output voltage error is only 0.2%, with a linearity of up to 0.01%.

For scalability, the circuit design supports a 3-bit hardware address, allowing up to 8 devices to be connected and operated simultaneously. The DAC2 Hat also incorporates safety features such as output short-circuit protection. In the event of a short circuit between the output pins and ground, it automatically enters a protective mode and shuts down the output to prevent damage.

DAC2 Hat is suitable for a variety of applications including general signal conversion, motor speed control, LED dimming, inverters, power supplies and industrial analogue signal isolation. It provides a reliable solution for converting digital signals to analogue, offering high accuracy, expandability and safety.and safety performance.

Address Select
By setting the A0, A1, A2 pins to high (1) or low (0), you get eight different I2C addresses from 0x58 to 0x5F. ** If the resistance is connected, it is regarded as high(1), and if the resistance is not connected, it is low(0) **.
