Designed for space-critical applications, the ADR5044 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 4.096 V, the advanced design of the ADR5044 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 ADR5044W are qualified for automotive applications and are available in a 3-lead SOT-23 package.
