MCHPMCP4922-E/P
Overview
The MCP4922-E/P is a dual-channel 12-bit voltage output Digital-to-Analog Converter (DAC) utilizing a resistor string architecture and SPI interface. This part features external voltage reference inputs and rail-to-rail output buffers, operating over a wide supply range of 2.7V to 5.5V.
Why Choose This Part
The MCP4922 offers high integration with two DAC channels in a single 14-DIP package, making it ideal for breadboard prototyping. It provides flexible output scaling with a selectable 1x or 2x gain and ensures low power consumption with a 2uA shutdown mode.
Applications
Key Specifications
Getting Started
To interface with the MCP4922, use a microcontroller with a standard SPI peripheral and a dedicated chip select line. Connect an external voltage reference to the VREF pins and utilize the LDAC pin to simultaneously update both analog outputs.
