Description:
This single-channel DAC module provides a precise and convenient method for generating analog voltage outputs. Communicating via PWM, it offers 8-bit resolution and a high accuracy of 0.2%, delivering selectable 0- 10V or 0- 5V industry-standard signals. This makes it perfectly suited for direct control of numerous 0- 10V or 0- 5V devices in automation scenarios, including lighting adjustment, frequency control, valve operation, and pump management, all programmable through Arduino.
The PWM interface simplifies control using standard MCU digital pins. As a member of a comprehensive DAC series, this module benefits from a wider ecosystem of analog output solutions featuring I2C or PWM control, voltage or current output options, 8, 12, and 15-bit resolutions, single or dual channels, and the potential for multi-channel expansion through cascading.
