Description

Designed for space-critical applications, the ADR5xx family are high precision shunt voltage references, housed in ultrasmall SC70 and SOT-23 packages. These references feature low temperature drift of 40 ppm/°C, an initial accuracy of better than 0.2%, and ultralow output noise of 14 V p-p.

Available in output voltages of 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V, the ADR5xx's advanced design eliminates the need for compensation by an external capacitor, yet the references are stable with any capacitive load. The minimum operating current increases from a mere 50 A to a maximum of 10 mA. This low operating current and ease of use make these references ideally suited for handheld, battery-powered applications.

A TRIM terminal is available on the ADR5xx to allow adjustment of the output voltage over a ±0.5% range, without affecting the temperature coefficient of the device. This feature provides users with the flexibility to trim out any system errors.
