Product Summary

The MCP4822 is a 12-Bit DACs with Internal VREF and SPI™ Interface. The MCP4822 of DACs provide 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 devices are available in the extended temperature range and PDIP, SOIC and MSOP packages.
