Operates from 2.7-5.5V with 175\u00b5A supply current. Features external voltage reference input, 4.5\u00b5s settling time, \u00b12 LSB INL, and rail-to-rail output buffer. E suffix denotes extended temperature range (-40 to 125\u00b0C), P suffix denotes PDIP-8 package. Part of the MCP4901\/4911\/4921 family (8\/10\/12-bit variants). Ideal for sensor calibration and set-point control.","working_principle":"The MCP4921 uses a resistor-string DAC architecture where the 12-bit digital code selects a tap point on a precision resistor ladder to produce the output voltage. The selected voltage is buffered by a rail-to-rail output amplifier that can drive loads as low as 1k\u03a9. The SPI interface accepts a 16-bit command word: 4 configuration bits (write\/ignore, buffered VREF, output gain 1x\/2x, shutdown) followed by 12 data bits. The LDAC pin allows synchronous update of the DAC output from the input register. The SHDN bit in the command word can place the device in 0.1\u00b5A shutdown mode while preserving the register contents.","pin_description":"
