3-Lead SC70 (KS) and 3-Lead SOT-23 (RT) 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 ADR5040W, ADR5041W, ADR5044W, and ADR5045W are qualified for automotive applications and are available in a 3-lead SOT-23 package.
