The MCP4821T-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 with support for up to 20 MHz clock speeds.
Key electrical specifications include a 12-bit resolution, a rail-to-rail output, and an internal 2.048V voltage reference. The device offers a selectable unity or 2x gain output and a fast settling time of 4.5 µs (typical). It supports single-supply operation and has an extended operating temperature range of -40°C to +125°C.
This DAC is suitable for applications requiring set point or offset trimming, sensor calibration, and precision selectable voltage references, particularly in portable instrumentation and battery-powered devices. The device is available in an 8-SOIC package and is designed for surface mounting.
Additional features include simultaneous latching of the DAC output with the LDAC pin, selectable active or shutdown modes for power savings, and a power-on reset (POR) circuit for reliable power-up. The architecture is based on a resistive string, providing low DNL error and a low ratio-metric temperature coefficient.
