The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ ADR4550 devices are high precision, low power, low noise voltage references featuring ±0.02% maximum initial error, excellent temperature stability, and low output noise. This family of voltage references uses an innovative core topology to achieve high accuracy while offering industry-leading temperature stability and noise performance. The low, thermally induced output voltage hysteresis and low long-term output voltage drift of the devices also improve system accuracy over time and temperature variations. A maximum operating current of 950 μA and a maximum low dropout voltage of 300 mV allow the devices to function very well in portable equipment.

The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ ADR4550 series of references are each provided in an 8-lead SOIC package and are available in a wide range of output voltages, all of which are specified over the extended industrial temperature range of −40°C to +125°C. The ADR4525W, available in an 8-lead SOIC package, is qualified for automotive applications.
