FoBE Breakout GP8403

I2C 0-5V/0-10V two channel DAC Module.​


FoBE Breakout GP8403 Main


Introduction​

The FoBE Breakout GP8403 integrates the Linearin GP8403 I2C to dual-channel voltage DAC converter and the ST M24C64 EEPROM for calibration data storage. The module converts 12-bit digital values (0x000-0xFFF) to precise 0-5V or 0-10V analog voltage output with excellent linearity and accuracy. Multiple connectivity options are provided for easy integration into various applications.

Applications​

  • General signal conversion and conditioning
  • Motor speed regulation and LED dimming control
  • Inverter and power supply control systems
  • Industrial analog signal isolation and processing
