The mikroE DAC Click Board is an easy and compact accessory board featuring MCP4921, a 12-bit single-channel digital-to-analog 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 communicates with the target board microcontroller using the SPI interface. The board contains two analog 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 with 5V systems.

With these features, DAC click is an ideal choice for applications like set point or offset trimming, precision selectable voltage reference, motor control feedback loop, digitally-controlled multiplier/divider, calibration of optical communication devices, and many more.

IC/Module: MCP4921 12-bit Digital-to-Analog Converter

MCP4921 is a single channel 12-bit digital-to-analog converter intended for low power consumption and high accuracy. Using the SPI protocols for communication, it operates from a single 2.7V to 5.5V supply. It includes double-buffered registers and features a resistive string architecture.

SMD Jumpers

DAC click features two SMD jumpers: PWR SEL and RERFERENCE. The zero-ohm PWR SEL jumper enables the user to select between a 3.3V and 5V power supply while the other zero-ohm jumper, REFERENCE, allows user to select either VCC or 4.096V as the voltage reference.
