ADR4525CRZ

Overview

The ADR4525CRZ is a high precision, low power, low noise voltage reference featuring an output voltage of 2.500 V and a maximum initial error of ±0.02%. It operates within an input voltage range of 3 V to 15 V and provides an output current capacity of +10 mA source and −10 mA sink. The device exhibits a temperature coefficient of 1 ppm/°C (box method) over the commercial range of 0°C to +70°C. Quiescent current is limited to 950 μA maximum, with a dropout voltage of 500 mV at no load.

Feature Summary

• Utilizes innovative core topology for industry-leading temperature stability and low noise performance.
• Features low thermally induced output voltage hysteresis and low long-term drift to improve system accuracy.
• Supports up to 10 mA sourcing and sinking output current capability.

Applications

• Precision data acquisition systems
• High resolution data converters
• Industrial instrumentation

Procurement Notes

Verify the specific grade suffix against the ordering guide to confirm the operating temperature range and package type. Ensure the selected variant matches the required thermal specifications for the target application environment. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select the ADR4525CRZ when a fixed 2.5 V reference is required with strict limits on initial accuracy and temperature drift. Consider the C grade specifically for commercial applications where operation between 0°C and +70°C is sufficient. Evaluate the low quiescent current and dropout voltage requirements relative to the available supply voltage headroom in the design.
