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.

No external components are needed to achieve full accuracy over the operating temperature range. Total supply current to the device, including the internal output buffer amplifier is typically 750µA.

The MX581 is designed for use with 8- to 14-bit ADCs and DACs as well as data acquisition systems. The reference is available in a 3-pin T0-39 metal can and an 8-pin SO surface-mount package.
