GENERAL DESCRIPTION
Designed for space critical applications, the ADR510 is a low
voltage (1.000 V), precision shunt-mode voltage reference in an
ultracompact (3 mm × 3 mm) SOT-23-3 package. The ADR510
features low temperature drift (70 ppm/°C), high accuracy
(±0.35%), and ultralow noise (4 μV p-p) performance.
The ADR510 advanced design eliminates the need for an external
capacitor, yet it is stable with any capacitive load. The minimum
operating current increases from 100 μA to a maximum of 10 mA.
This low operating current and ease of use make the ADR510
ideally suited for handheld battery-powered applications.
A TRIM terminal is available on the ADR510 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.
