Precision Voltage Control for Every Channel: Enhance Your I2C Projects with the 7Semi DAC7578 Breakout
Take full command of your multi-channel analog output needs with the 7Semi DAC7578 Breakout – 8 Channel 12bit I2C DAC, engineered for seamless voltage control, high-resolution output, and reliable integration across a wide variety of microcontrollers and microcomputers. This breakout board features eight 12-bit DAC channels, each capable of delivering stable and precise analog signals—making it ideal for applications in industrial control, instrumentation, signal generation, and analog signal interfacing.
Powered by the Texas Instruments DAC7578, this low-power, voltage-output DAC supports both 3.3V and 5V power and logic levels, offering unmatched flexibility. The device is ratiometric, meaning output ranges from 0V to the voltage reference (VRef), which defaults to the power supply but can be reconfigured for custom voltage ranges. Whether you're generating precision signals or controlling analog devices, this breakout ensures glitch-free performance with excellent linearity and minimal transient voltages. The onboard power-on-reset (POR) circuit ensures safe start-up states by setting all outputs to zero-scale or midscale until a valid digital command is received.
Key Features of the 7Semi DAC7578 Breakout:
-
8 Independent 12-bit DAC Channels
Control up to eight separate analog outputs with high precision from a single board.
-
I2C-Compatible Interface
Communicate over standard I2C protocol at speeds up to 3.4 MHz, compatible with most microcontrollers and SBCs like Arduino, Raspberry Pi, STM32, and ESP32.
-
Wide Voltage Support (3.3V / 5V)
Operates flawlessly with 3.3V or 5V logic and power levels, adapting to your system’s requirements without level shifters.
-
Flexible Reference Voltage (VRef)
Default VRef tied to power pin; can be customized via jumper to match specific voltage references like 4.095V for high-accuracy outputs.
-
Power-On Reset Protection
Built-in POR circuitry ensures all DAC channels safely initialize to known states (zero-scale or midscale) on startup.
-
Low Glitch, High Linearity Performance
Monolithic architecture minimises code-to-code transients for clean, stable output signals ideal for sensitive applications.
-
Compact Breakout Board Format
Breadboard-friendly design for quick prototyping and seamless integration into embedded hardware systems.
-
Multi-Device I2C Bus Sharing
Multiple DAC7578 breakouts can share a single I2C bus, making it easy to expand your system with more channels.
