MCP4921E/SN 12-bit SPI DAC SMD IC - 10 Pack


Now available from PMD Way is the Microchip MCP4921-E/P 12-bit SPI DAC IC as SOP8 surface-mount packaging in packs of ten.

This allows you to generate analogue signals with 12-bit accuracy from your micrcontroller-based project. 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 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.
