Adafruit DAC7578 Breakout - 8 Channel 12-bit I2C DAC STEMMA QT / Qwiic

The Adafruit DAC7578 Breakout board features eight 12-bit digital-to-analog converters (DACs) controlled over I2C, perfect for precise voltage output needs. Compatible with both 3.3V and 5V power and logic levels, it delivers ratiometric voltage outputs aligned with the reference voltage.

Key benefits include easy integration with microcontrollers or microcomputers via STEMMA QT/Qwiic connectors, and the flexibility to set the output voltage reference by cutting a jumper or supplying an external voltage.

• Eight 12-bit DAC channels accessible through I2C interface.
• Compatible with 3.3V or 5V power and logic.
• Ratiometric output voltage with configurable reference.
• Populated with support circuitry for microcontroller integration.
• Includes SparkFun Qwiic/STEMMA QT JST SH connectors for easy I2C bus sharing.
• Supported with Arduino, CircuitPython, and Python drivers, wiring diagrams, and example code.
