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.
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
V S
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.
