Pin-Programmable Precision Voltage Reference

Maxim's MX584 is a temperature-compensated, bandgap voltage reference which provides pin-programmable output voltages of +10.00V, +7.50V, +5.00V, and +2.50V. External components are not required for these outputs, but if other voltages are desired, they can be programmed with external resistors.

Laser trimming minimizes output error as well as temperature drift, to as low as 10mV and 15ppm/°C with the MX584K.

The input voltage range of the MAX584 is 4.5V to 30V. The reference also includes a STROBE input which shuts down the reference output. Typical current drain when ON is 750µA. This drops to about 100µA when the reference is strobed OFF.

The MX584 is designed for use with 8- to 14-bit A/D and D/A converters as well as data acquisition systems. It is available in 8-lead TO-99 metal cans, plastic DIPS, CERDIPS, and SO packages.
