ADI ADR4520ARZ-R7

The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ ADR4550 devices are high precision, low power, low noise voltage references featuring ±0.02% B,C,and D grade 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 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
