Precision, Micropower Shunt Mode Voltage References Data Sheet ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 FEATURES PIN CONFIGURATION ADR5040/ADR5041/ Ultracompact SC70 and SOT-23 packages ADR5043/ADR5044/ Low temperature coefficient: 75 ppm/C (maximum) ADR5045 Pin compatible with LM4040/LM4050 V+ 1 Initial accuracy: 0.1% No external capacitor required 3 T Wide operating current range: 50 A to 15 mA V 2 Extended temperature range: 40C to +125C Qualified for automotive applications NOTES 1. IT IS RECOMMENDED THAT PIN 3 BE CONNECTED TO V+. APPLICATIONS Figure 1. 3-Lead SC70 (KS) and 3-Lead SOT-23 (RT) Portable, battery-powered equipment Automotives Power supplies Data acquisition systems Instrumentation and process control Energy management GENERAL DESCRIPTION Designed for space-critical applications, the ADR5040/ Table 1. Selection Table ADR5041/ADR5043/ADR5044/ADR5045 are high precision Initial Temperature shunt voltage references, housed in ultrasmall SC70 and SOT-23 Accuracy (%) Coefficient (ppm/C) Device Voltage (V) packages. These voltage references are multipurpose, easy-to-use ADR5040A 2.048 0.2 100 ADR5040B 2.048 0.1 75 references that can be used in a vast array of applications. They ADR5041A 2.5 0.2 100 feature low temperature drift, an initial accuracy of better than ADR5041B 2.5 0.1 75 0.1%, and fast settling time. ADR5043A 3.0 0.2 100 Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and ADR5043B 3.0 0.1 75 5.0 V, the advanced design of the ADR5040/ADR5041/ADR5043/ ADR5044A 4.096 0.2 100 ADR5044/ADR5045 eliminates the need for compensation by an ADR5044B 4.096 0.1 75 external capacitor, yet the references are stable with any capacitive ADR5045A 5.0 0.2 100 ADR5045B 5.0 0.1 75 load. The minimum operating current increases from 50 A 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 40C to +125C. The ADR5040W, ADR5041W, ADR5044W, and ADR5045W are qualified for automotive applications and are available in a 3-lead SOT-23 package. Rev.
