GENERAL DESCRIPTION

Designed for space-critical applications, the ADR520/ADR525/

ADR530/ADR540/ADR550 are high precision shunt voltage

references, housed in ultrasmall SC70 and SOT-23-3 packages.

These references feature low temperature drift of 40 ppm/°C, an

initial accuracy of better than 0.2%, and ultralow output noise

of 14 μV p-p.

Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and

5.0 V, the ADR5xx’s advanced design eliminates the need for

compensation by an external capacitor, yet the references are

stable with any capacitive load. The minimum operating

current increases from a mere 50 μA to a maximum of 15 mA.

This low operating current and ease of use make these

references ideally suited for handheld, battery-powered

applications.

A trim terminal is available on the ADR5xx to allow adjustment

of the output voltage over a ±0.5% range, without affecting the

temperature coefficient of the device. This feature provides users

with the flexibility to trim out any system errors.
