Good value

Solid performance for the price. Soldering pads are a bit small but manageable with a fine tip.

5 FAQ

Q: Does it save the output value after power loss?

A: Yes, the internal EEPROM allows you to store the DAC settings so they persist after power is removed.

Q: Is this compatible with 3.3V logic levels?

A: Yes, the module supports supply voltages from 2.7V to 5.5V, making it compatible with 3.3V systems.

Q: Are there Arduino libraries available for this?

A: Yes, there are several open-source libraries available that support the MCP4725 chip on Arduino.

Q: What is the maximum output current?

A: This is a voltage output DAC intended for high impedance loads. It is not designed to drive high current loads directly.

Q: Can I connect multiple modules on the same bus?

A: Yes, you can connect multiple modules by configuring different I²C addresses using the ADDR pin.
