FoBE Breakout GP8303

I2C 4-20mA/0-20mA DAC Module.

Introduction

The FoBE Breakout GP8303 integrates the Linearin GP8303 I2C to 4-20mA DAC converter and the EEPROM for calibration data storage. The module converts 12-bit digital values (0x000-0xFFF) to precise 4-20mA analog current output with excellent linearity of 0.1%. Multiple connectivity options are provided for easy integration into various applications.

Applications

• Function signal generators and test equipment
• Automatic controllers for lighting and fountain systems
• Industrial automation and process control
• Electromechanical equipment debugging and calibration
• Small-scale testing and measurement devices
