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. Ta ble 1.

ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 Data Sheet Rev. E | Page 10 of 14 TERMINOLOGY Temperature Coefficient The change in output voltage with respect to operating temperature changes. It is normalized by an output voltage of 25°C. This parameter is expressed in ppm/°C and is determined by the following equation: ( ) ( ) ( ) ( ) 610C25C ppm ×−×° −= ° 12UTO 1OUT2OUT OUT TTV TVTVTCV (1) where: VOUT(25°C) = VOUT at 25°C. VOUT(T1) = VOUT at −40°C. VOUT(T2) = VOUT at 125°C. Thermal Hysteresis The change in output voltage after the device is cycled through temperatures ranging from +25°C to −40°C, then to +125°C, and back to +25°C. This is common in precision reference and is caused by thermal-mechanical package stress. Changes in envi- ronmental storage temperature, board mounting temperature, and the operating temperature are some of the factors that can contribute to thermal hysteresis. The following equation expresses a typical value from a sample of parts put through such a cycle: ( ) [ ] ( ) ( ) 10C25 C25ppm C25 −°= −°= OUT TCOUTOUT HYSOUT TCOUTOUTHYSOUT V VVV VVV (2) where: VOUT(25°C) = VOUT at 25°C. VOUT_TC = VOUT at 25°C after a temperature cycle from +25°C to −40°C, then to +125°C, and back to +25°C.
