GENERAL DESCRIPTION

A TRIM terminal is available on the ADR512 to provide adjust-

ment of the output voltage over Ϯ0.5% without affecting the

temperature coefficient of the device. This feature provides

users with the flexibility to trim out any system errors.

Designed for space critical applications, the ADR512 is a low

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

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

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

(Ϯ0.30%), and ultralow noise (4 ␮V p-p) performance.

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 ␮A to a

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

make the ADR512 ideally suited for handheld battery-powered

applications.
