GENERAL DESCRIPTION

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.

The ADR4525, ADR4540, and ADR4550 are also available in D,

which are in 8 lead LCC package, and C grade with a temperature

range of 0°C to 70°C. The ADR4525W, available in an 8-lead

SOIC package, is qualified for automotive applications.
