FoBE Breakout GP8403

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


FoBE Breakout GP8403 Main

Introduction​

FoBE Breakout GP8403 can convert I2C signals into analog signals, and can linearly convert 12-bit digital values 0x000-0xFFF into 0-5V or 0-10V analog Voltage; The Output voltage error: < 0.5%.

There is an eeprom on board, can store the calibration parameter.

Applications​

  • General signal conversion
  • Motor speed regulation, LED dimming
  • Inverter, power supply
  • Industrial analog signal isolation

Key Features​

  • GP8403:

    • GP8403 uses I2C interface to linearly convert two analog voltage outputs of 0-5V or 0-10V.
    • Input signal range 12Bit, 0x000-0xFFF
    • 0-5V/0-10V output voltage is controlled by internal data
    • Input I2C signal high level: 2.7V-5.5V
    • Output voltage error: < 0.5% (can reach 0.1% TPY after two-point calibration)
    • Output voltage linearity error: 0.1% (TPY)
    • Output short circuit protection, when the output pin is short-circuited to ground, the chip enters protection mode and stops output.
    • Power supply voltage: 9V-36V
    • Power consumption: < 5mA
    • Start-up time: < 2ms
    • Operating temperature: -40°C to 85°C

  • EEPROM:

    • 64 Kbit (8 Kbyte) of EEPROM
    • Page size: 32 byte
    • Write protect of the whole memory array
    • Enhanced ESD/Latch-Up protection
    • More than 4 million Write cycles
    • More than 200-years data retention

  • Connectivity:

    • Two 4Pin SH1.0 Connectors(IIC)
    • 6Pin 2.54mm Header Holes (IIC + 2 x NC)
    • Output by 4 x 3.81mm Screw terminal block
