GENERAL DESCRIPTION
Designed for space-critical applications, the ADR5040/
ADR5041/ADR5043/ADR5044/ADR5045 are high precision
shunt voltage references, housed in ultrasmall SC70 and SOT-23
packages. These voltage references are multipurpose, easy-to-use
references that can be used in a vast array of applications. They
feature low temperature drift, an initial accuracy of better than
0.1%, and fast settling time.
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 ADR5040/ADR5041/ADR5043/
ADR5044/ADR5045 eliminates the need for compensation by an
external capacitor, yet the references are stable with any capacitive
load. The minimum operating current increases from 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. This family of references has been characterized
over the extended temperature range of −40°C to +125°C. The
ADR5041W and the ADR5044W are qualified for automotive
applications and are available in a 3-lead SOT-23 package.
