DAC Click Board

The MikroE DAC Click Board™ is an easy and compact accessory board featuring MCP4921, a 12-bit single-channel digital-to-analogue converter. Designed to ensure high accuracy and low noise performance, the MCP4921 module is a suitable choice for industrial applications where calibration or compensation of signals, such as temperature, pressure, and humidity. It operates an optional 2x buffered output. DAC Click Board™ communicates with the target board microcontroller using the SPI interface. The board contains two analogue output screw terminals: Vout and GND. These data are 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. The board is designed to operate a 3.3V power supply by default. The user can solder the PWR SEL zero-ohm SMD jumper to the 5V position when using 5V systems. With these features, DAC Click Board™ is an ideal choice for applications like setpoint or offset trimming, precision selectable voltage reference, motor control feedback loop, digitally-controlled multiplier/divider, calibration of optical communication devices, and many more.
