MCP4725 I2C 12-Bit DAC Breakout Module — True Analogue Voltage Output
The MCP4725 converts a 12-bit digital value received over I2C into a true analogue voltage output, giving any Arduino or ESP32 a genuine DAC output with 4096 steps from 0V to VCC. Unlike PWM-based pseudo-analogue outputs, the MCP4725 output is a steady DC voltage requiring no filtering capacitor for most applications. An onboard EEPROM stores the last written value and restores it at power-up.
- 12-bit DAC — 4096 steps, 0V to VCC output
- I2C interface — address 0x60 or 0x61
- EEPROM — retains last output value at power-up
- 2.7V–5.5V supply
- Fast settling time — 6 microseconds to 0.5 LSB
