Product Summary

The mcp4822 is a 2.7V–5.5V, low-power, low DNL, 12-bit Digital-to-Analog Converter (DAC) with internal band gap voltage reference, optional 2x-buffered output and Serial Peripheral Interface (SPI.). The mcp4822 provides high accuracy and low noise performance for industrial applications where calibration or compensation of signals (such as temperature, pressure and humidity) are required. The mcp4822 is available in the extended temperature range and PDIP, SOIC and MSOP packages. The applications of the mcp4822 include Set Point or Offset Trimming, Sensor Calibration, Precision Selectable Voltage Reference, Portable Instrumentation (Battery-Powered), Calibration of Optical Communication Devices.
