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 advanced design of the ADR520/ADR525/
ADR530/ADR540/ADR550 eliminates the need for compensa-
tion 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 ADR520/ADR525/ADR530/
ADR540/ADR550 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.
