DAC3 click carries Microchip’s MCP4726 IC, a 12-bit digital-to-analog converter, along with voltage output screw terminals. The digital value is converted to the appropriate voltage level in the range between GND and REFERENCE (VCC or 4.096V), which is proportional to the received 12-bit number. MCP4726 also integrates EEPROM for storing DAC register and configuration bit values. The board communicates with the target board MCU through the mikroBUS I2C interface (SCL, SDA pins). Standard (100 kHz), fast (400 kHz) and highspeed (3.4 MHz) I2C modes are available. Uses either a 3.3V or a 5V power supply.
