Product Introduction
The 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.
The MCP482X devices are available in the extended temperature range and PDIP, SOIC and MSOP packages.
The MCP482X devices utilize a resistive string architecture, with its inherent advantages of low DNL error, low ratio metric temperature coefficient and fast settling time. These devices are specified over the extended temperature range. The MCP482X family includes double-buffered registers, allowing simultaneous updates using the LDAC pin. These devices also incorporate a Power-On Reset (POR) circuit to ensure reliable power-up.
