ADI ADR525BKSZ-REEL7

Designed for space- critical applications, the ADR520/ADR525/ ADR530/ADR540/ADR550 are high precision shunt voltage references, housed in ultrasmall SC70 and SOT- 23- 3 packages. These references feature low temperature drift of 40ppm / °C, an initial accuracy of better than ±0.2%, and ultralow output noise of 14μV p- p. Available in output voltages of 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V, the advanced design of the ADR520/ADR525/ ADR530/ADR540/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 50μA 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 ADR520/ADR525/ADR530/ ADR540/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 any system errors.
