MCP4922-E/SL

The MCP4922-E/SL from Microchip Technology is a dual 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It is designed for applications requiring precise signal control and operates from a single 2.7V to 5.5V power supply.

Key electrical specifications include a 12-bit resolution, a fast settling time of 4.5 µs, and selectable unity or 2x gain output. The device utilizes an SPI compatible serial peripheral interface for communication and supports external voltage references. Its architecture is based on a resistive string, contributing to low Differential Nonlinearity (DNL) errors.

This DAC is housed in a 14-SOIC package and is designed for surface mount applications. It operates across an extended temperature range of -40°C to +125°C, making it suitable for various industrial and consumer environments. The device offers dual DAC channels, allowing for simultaneous updates via the LDAC pin.

Applications for the MCP4922-E/SL include set point or offset trimming, precision selectable voltage references, motor control feedback loops, and digitally-controlled multipliers or dividers. Its high accuracy and low noise performance are beneficial for calibration and compensation tasks in systems measuring temperature, pressure, or humidity.
