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/ADR5043/ADR5044/ADR5045 family at www.analog.com.
