ADR525BRTZ-REEL7: High Precision Shunt Mode Voltage Reference (2.5 V)
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 40 ppm/°C, an initial accuracy of better than ±0.2%, and ultralow output noise of 14 μV p-p.
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 ADR520/ADR525/ ADR530/ADR540/ADR550 eliminates the need for compensa-tion 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 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.
