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.
