Adafruit MCP4725 DAC
DESCRIPTION
This module makes it easy to add an analog output to your microcontroller by digital-to-analog conversion based on the MCP4725, a controllable 12-bit DAC in I2C easy to implement.
Very useful in audio/analog when the PWM is not enough, just choose an output value and it will be available on the Vout.
It is possible to control 2 modules by the same I2C bus.
TECHNICAL FEATURES
Dimensions 0.71"x0.55"x0.1" (18x14x3mm)
Compatible with 3.4Mbps fast mode I2C.
EEPROM on the card to keep the selected voltage value in memory
Compatible with 3.3V to 5V (the selected output voltage cannot exceed the supply voltage)
