Description

Hat DAC is a DA conversion module compatible with M5SticKC, internally integrated with the DAC conversion chip MCP4725. It features low power consumption, high precision, single-channel, 12-bit buffered voltage output digital-to-analog converter (DAC), and non-volatile memory (EEPROM). Its on-chip precision output amplifier allows it to achieve rail-to-rail analog output swing. Users can use I2C interface commands to write DAC input and configuration to non-volatile memory (EEPROM), allowing the DAC to retain the code during power-off and be ready for use upon power-up. The I2C address is 0x60.
