MCHPMCP4822-E/P
Overview
The MCP4822-E/P is a dual-channel 12-bit voltage output digital-to-analog converter (DAC) that utilizes an internal voltage reference for simplified circuit design. It features a buffered string DAC architecture and communicates over a standard SPI interface, operating across a wide supply range of 2.7V to 5.5V.
Why Choose This Part
This DAC is an excellent choice for prototyping due to its 8-pin PDIP package which is breadboard-friendly. It eliminates the need for an external reference while maintaining a fast 4.5us settling time and low power consumption, making it highly efficient for space-constrained designs.
Applications
Key Specifications
Getting Started
To begin development, interface the MCP4822-E/P with any microcontroller using a 3-wire SPI bus and a chip select (CS) line. Since it uses an internal 2.048V reference, ensure your software logic accounts for the selectable gain (1x or 2x) to set the full-scale output range.
