Product Summary

The mcp4922 is a 12-Bit DAC with SPI Interface. The mcp4922 provides high accuracy and low noise performance for industrial applications where calibration or compensation of signals (such as temperature, pressure and humidity) are required. Applications of the mcp4922 include: Set Point or Offset Trimming, Sensor Calibration, Digitally-Controlled Multiplier/Divider, Portable Instrumentation (Battery-Powered) and Motor Feedback Loop Control.
