Unit DAC2
Description
DAC2 Unit is an I2C digital-to-analog signal conversion unit. It utilizes the GP8413 solution, which provides high precision and accuracy in its performance. This chip can linearly convert a 15-bit digital value into two independent analog voltages of 0-5V or 0-10V. The output voltage error is only 0.2%, and it achieves linearity of up to 0.01%.
In terms of scalability, the circuit design supports a 3-bit hardware address, allowing up to 8 devices to be connected and operated simultaneously. The DAC2 Unit also incorporates safety features such as output short-circuit protection. When there is a short circuit between the output pins and ground, it automatically enters a protection mode, ceasing the output to prevent damage.
DAC2 Unit finds applications in various fields, including general signal conversion, motor speed control, LED dimming, inverters, power supplies, and industrial analog signal isolation. It provides a reliable solution for converting digital signals to analog, offering high precision, reliability, and expandability.
