MCP4821-E/P Description

Short technical summary and product information.

The MCP4821-E/P from Microchip Technology is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It operates from a single supply voltage ranging from 2.7V to 5.5V and utilizes an SPI-compatible serial peripheral interface with support for up to 20 MHz clock speeds.

 

This DAC boasts a fast settling time of 4.5 µs (typical) and includes a high-precision 2.048V internal voltage reference. The output type is voltage-buffered, and it offers a selectable unity or 2x gain for the full-scale range. The device also supports simultaneous latching of the DAC output using the LDAC pin and incorporates a Power-on Reset (POR) circuit for reliable power-up.

 

Designed for applications requiring set point or offset trimming, sensor calibration, or a precision selectable voltage reference, the MCP4821-E/P is specified for an extended temperature range of -40°C to +125°C. It is housed in an 8-pin PDIP package suitable for through-hole mounting.

 

Key electrical characteristics include a 12-bit resolution, a typical settling time of 4.5 µs, and an operating voltage range of 2.7V to 5.5V. The internal voltage reference is 2.048V, and the output is rail-to-rail. The device uses a resistive string architecture, contributing to low DNL error and fast settling.
