Precision Micropower Shunt Mode Voltage Reference Applications (2.048 V)

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.
