The MCP4821-E/MS from Microchip Technology is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). It operates from a single 2.7V to 5.5V supply and utilizes an SPI-compatible serial peripheral interface with support for up to 20 MHz clock speeds.
This DAC features a high-precision internal voltage reference of 2.048V, with selectable unity or 2x gain for the full-scale output range. It offers a fast settling time of 4.5 µs and a rail-to-rail output. The device includes double-buffered registers for synchronous updates using the LDAC pin and incorporates a Power-on Reset (POR) circuit for reliable power-up.
Specified for an extended temperature range of -40°C to +125°C, the MCP4821-E/MS is suitable for applications requiring signal calibration or compensation, such as set point or offset trimming, sensor calibration, and precision selectable voltage references. It is available in an 8-MSOP package and supports surface mount.
The device architecture is based on a resistive string, providing advantages like low DNL error, low ratio-metric temperature coefficient, and fast settling times. It can be operated in active or shutdown modes for power savings.
