The MCP4921 device is a single channel 12-bit DAC which uses an external voltage reference. This device offers high accuracy and low power consumption, and is available in various packages. Communication with the device is accomplished via a simple serial interface using SPI protocols. The MCP4921 device is a part of the MCP4901/MCP4911/MCP4921 product family, which are single channel 8-bit/10-bit/12-bit DACs which use external voltage reference (VREF). These devices provide very high accuracy and low noise performance, and are suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications. The low power consumption and small package options make these devices very attractive for many portable and battery-powered applications. If two outputs are needed then the MCP4902/412/4922 dual channel product family can be used.
