Gravity GP8413 2-Channel I2C to 0-5V/10V DAC Module

The Gravity DAC module from DFRobot uses the GP8413 chip to generate two analog voltages of 0 to 5 V or 0 to 10 V, controlled via I2C. The resolution is 15 bit (values 0 to 32767), the error of the output voltage is below 0.2 %, the linearity error 0.01 %. This allows devices with a 0-10 V control input to be driven, for example frequency inverters, dimmers, valves and pumps.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Recommended Accessories:

• Dupont Cables M-M 10cm 20 Pieces
• Gravity IO Expansion Shield for Arduino V7.1
• Gravity I2C HUB

Features:

• 2 voltage outputs VOUT0 and VOUT1 with common GND
• Range 0 to 5 V or 0 to 10 V, set by software
• Resolution 15 bit, error below 0.2 %, linearity error 0.01 %
• 8 I2C addresses 0x58 to 0x5F via the switches A0 to A2: up to 8 modules and thus 16 channels on one bus
• Supply 3.3 V to 5 V
• Gravity I2C 4-pin (+, −, C for SCL, D for SDA)
• Arduino library DFRobot_GP8XXX for the entire DAC series from DFRobot

Application Examples:

• Lighting control with 0-10 V dimmers
• Speed setpoint for frequency inverters
• Valve and pump control
• Laboratory setups and test equipment
