• Manufacturer Part Number: MX581
• Description: Mx581 High-precision, 10v Reference
• Manufacturer: Maxim Integrated Products, Inc.

Maxim’s MX581 is a three-terminal, temperature-
compensated, bandgap voltage reference which pro-
vides 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.
