Overview
The ADR525ARTZ-REEL7 is a high precision shunt mode voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 2.5 V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 70 ppm/°C. The device operates within an industrial temperature range of −40°C to +85°C and requires a minimum operating current of 50 μA, supporting up to 15 mA. Housed in a compact 3-Lead SOT-23-3 package, it eliminates the need for external compensation capacitors while remaining stable with any capacitive load.
Feature Summary
- Ultracompact 3-Lead SOT-23-3 package designed for space-critical applications
- Capable of trimming the output voltage over a ±0.5% range without affecting the temperature coefficient
- Operates stably without requiring an external compensation capacitor
Applications
- Portable, battery-powered equipment
- Automotive systems
- Data acquisition systems
- Instrumentation and process control
- Energy measurement
Procurement Notes
Verify the specific Grade A designation associated with the ART suffix to confirm the 70 ppm/°C temperature coefficient and ±0.4% initial accuracy specifications. Ensure the REEL7 packaging option aligns with automated surface-mount assembly requirements. Confirm RoHS compliance status via the Z suffix if required by environmental regulations.
Selection Notes
Select this component when a precise 2.5 V reference is needed in a minimal footprint. The Grade A variant offers higher temperature stability compared to Grade B options. Consider the trim terminal functionality if system-level calibration is necessary to compensate for board-level errors or load variations.
Part Context
This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt voltage references. These devices utilize band gap concepts to produce stable outputs suitable for high accuracy data acquisition components. The series is pin-compatible with LM4040/LM4050 devices, facilitating direct upgrades in existing designs.
Replacement Considerations
Pin-compatible alternatives include the LM4040 and LM4050 series. Other shunt references from the same family, such as the ADR520, ADR530, ADR540, or ADR550, may be used if different output voltages are acceptable.
