ADR530:  High Precision Shunt Mode Voltage Reference (3.0 V)

Product Details


Designed for space-critical applications, the ADR525/ADR530/ ADR550 are high precision shunt voltage references, housed in ultrasmall SC70 and SOT-23-3 packages. These references feature low temperature drift of 40 ppm/°C, an initial accuracy of better than ±0.2%, and ultralow output noise of 18 μV p-p.

Available in output voltages of 2.5 V, 3.0 V, and 5.0 V, the advanced design of the ADR525/ADR530/ADR550 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 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.

A trim terminal is available on the ADR525/ADR530/ADR550 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 small system errors.

For better initial accuracy and wider temperature range, see the ADR5040/ADR5041/ADR5043ADR5044/ADR5045 family at www.analog.com.
