Description

DAC Hat is a DA (digital-to-analog) conversion module compatible with M5StickC. It integrates the MCP4725 DAC conversion chip, offering low power consumption, high precision, a single channel, and a 12-bit buffered voltage output DAC. It also includes non-volatile memory (EEPROM) functionality.

The on-chip precision output amplifier allows for rail-to-rail analog output swing. Users can utilize the I2C interface commands to input DAC values and configure settings, which are then written to the non-volatile memory (EEPROM). This ensures that the DAC retains its settings even during power loss and can be used directly upon power-up. The I2C address for the DAC Hat is 0x60.
