GENERAL DESCRIPTION

Designed for space critical applications, the ADR512 is a low

voltage (1.200 V), precision shunt-mode voltage reference in the

ultracompact (3 mm × 3 mm) SOT-23 package. The ADR512

features low temperature drift (60 ppm/°C), high accuracy

( 0.30%), and ultralow noise (4 µV p-p) performance.

maximum of 10 mA. This low operating current and ease of use

make the ADR512 ideally suited for handheld battery-powered

applications.

A TRIM terminal is available on the ADR512 to provide

adjustment of the output voltage over 0.5% without affecting

the temperature coefficient of the device. This feature provides

users with the flexibility to trim out any system errors.

The ADR512’s advanced design eliminates the need for an

external capacitor, yet it is stable with any capacitive load. The

minimum operating current increases from a scant 100 µA to a
