references that can be used in a vast array of applications. They ADR5040A 2.048 ±0.2 100 feature low temperature drift, an initial accuracy of better than ADR5040B 2.048 ±0.1 75 0.1%, and fast settling time. ADR5041A 2.5 ±0.2 100 Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and ADR5041B 2.5 ±0.1 75 5.0 V, the advanced design of the ADR5040/ADR5041/ADR5043/ ADR5043A 3.0 ±0.2 100 ADR5044/ADR5045 eliminates the need for compensation by an ADR5043B 3.0 ±0.1 75 external capacitor, yet the references are stable with any capacitive ADR5044A 4.096 ±0.2 100 load. The minimum operating current increases from 50 µA to ADR5044B 4.096 ±0.1 75 a maximum of 15 mA. This low operating current and ease of use ADR5045A 5.0 ±0.2 100 make these references ideal y suited for handheld, battery-powered ADR5045B 5.0 ±0.1 75 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.
