GENERAL DESCRIPTION
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 is provided in an 8-lead SOIC
package and is 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.
