The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ADR4550 devices are high precision, low power, low noise voltage references featuring ±0.02% C 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 overtime and temperature variations.
A maximum operating current of 950 μA and a maximum low dropout voltage of 300 mV allow the devices to function verywell 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 ADR4525, ADR4540, and ADR4550 are also available in 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.
