General Description

The Microchip Technology Inc.

MCP482X devices are 2.7V–5.5V, low-power, low DNL, 12-bit Digital-to-Analog Converters (DACs) with internal band gap voltage reference, optional 2x-buffered output and Serial Peripheral Interface (SPI™).

The MCP482X family 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.
