The MCP4821-E/SN 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 for communication, supporting clock speeds up to 20 MHz.
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 (typical) and a rail-to-rail output. The device includes double-buffered registers for synchronous updates via the LDAC pin and incorporates a Power-on Reset (POR) circuit for reliable power-up.
The MCP4821-E/SN is specified for an extended temperature range of -40°C to +125°C. Its resistive string architecture provides low DNL error and a low ratio-metric temperature coefficient. Applications include set point or offset trimming, sensor calibration, and precision selectable voltage references, particularly in portable instrumentation.
This component is available in an 8-SOIC package and is designed for surface mount applications. It supports a single-supply operation and offers selectable gain options, making it versatile for various calibration and signal conditioning tasks.
