GENERAL DESCRIPTION

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.
