General Description
Maxim’s MX581 is a three-terminal, temperaturecompensated, bandgap voltage reference which provides a precision 10V output from an unregulated input of 12.5V to 30V. Laser trimming is used to minimize initial error and temperature drift, to as low as 10mV and 15ppm/°C with the MX581.

Features
♦ ±10mV Tolerance (MX581K)
♦ Low Tempco—15ppm/°C max (MAX581K)
♦ No External Components or Trims
♦ Short-Circuit Proof
♦ Output Sources and Sinks Current
♦ 10mA Output Current
♦ Low-Supply Current—1.0mA (max)
♦ Three-Terminal Package

Applications
    CMOS DAC Reference
    A/D Converter Reference
