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 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 10 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.
