The MCP4921-E/SN from Microchip Technology is a 12-bit, single-channel, buffered voltage output Digital-to-Analog Converter (DAC). It is designed for applications requiring precise signal calibration and compensation.
This DAC 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. The device offers a selectable unity or 2x gain for its output, and features a fast settling time of 4.5 µs. It includes double-buffered registers for synchronous updates via the LDAC pin and incorporates a Power-on Reset (POR) circuit for reliable power-up.
The MCP4921-E/SN is specified for an extended temperature range of -40°C to +125°C, making it suitable for demanding industrial environments. Its resistive string architecture contributes to low Differential Non-Linearity (DNL) error and high accuracy. The device is available in an 8-SOIC package, suitable for surface mounting.
Key electrical specifications include a 12-bit resolution, a supply voltage range of 2.7V to 5.5V, and an external voltage reference input. The output is voltage buffered and not differential. The device is designed for general-purpose applications where accurate digital-to-analog conversion is required.
