The MCP4821-E/MC 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 fast settling time of 4.5 µs, a selectable unity or 2x gain output, and a high-precision internal voltage reference of 2.048V. The device offers a rail-to-rail output and operates within an extended temperature range of -40°C to +125°C.
This DAC is designed for applications requiring set point or offset trimming, sensor calibration, and precision selectable voltage references, particularly in portable instrumentation and battery-powered devices. It is available in an 8-DFN (2x3) package suitable for surface mounting.
The device incorporates double-buffered registers for synchronous DAC output updates using the LDAC pin and includes a Power-on Reset (POR) circuit for reliable power-up. Its resistive string architecture contributes to low DNL error, a low ratio metric temperature coefficient, and fast settling times.
