† Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

The Microchip Technology Inc. MCP4922 are 2.7 5.5V, low-power, low DNL, 12-Bit Digital-to-Analog Converters (DACs) with optional 2x buffered output and SPI interface.

The MCP4922 are DACs that 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 MCP492X are available in the extended temperature range and PDIP, SOIC, MSOP and TSSOP packages.

The MCP4922 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 MCP492X include doublebuffered inputs, allowing simultaneous updates using theLDAC pin. These devices also incorporate a Power-On Reset (POR) circuit to ensure reliable power-up.
