Overview
The ADR3525WBRMZ-R7 is a micropower, high-precision CMOS voltage reference with a nominal output of 2.5 V. It features a maximum temperature coefficient of 5 ppm/°C and an initial output voltage error of ±0.1%. The device operates within an input voltage range of 2.7 V to 5.5 V and supports an operating temperature range from −40°C to +125°C. It provides an output current capacity of +10 mA source and −3 mA sink, with a maximum quiescent current of 100 μA. The component is qualified for automotive applications under AEC-Q100 standards.
Feature Summary
- Utilizes proprietary DigiTrim technology for digital trimming of output voltage and temperature coefficient during final assembly.
- Features low long-term drift and low output voltage hysteresis to improve lifetime system accuracy.
- Includes an enable pin that allows the device to be shut down, reducing quiescent current to 5 μA.
Applications
- Automotive battery monitors
- Portable instrumentation
- Process transmitters
- Remote sensors
- Medical instrumentation
Procurement Notes
Verify the specific grade (B grade) and package suffix (RM-8 MSOP) against the datasheet ordering guide. Confirm the reel packaging designation matches the required supply format. Ensure the automotive qualification status meets project requirements before integration.
Selection Notes
Select this model for applications requiring a 2.5 V reference with strict temperature stability limits. The B grade specification ensures a maximum temperature coefficient of 5 ppm/°C. Consider the low dropout voltage and current sourcing capabilities when designing power supply constraints.
Part Context
This component belongs to the ADR35xx series of micropower voltage references manufactured by Analog Devices Inc. The series includes variants with different output voltages such as 3.0 V, 3.3 V, 4.096 V, and 5.0 V. All members share similar architectural features including CMOS construction and automotive qualification.
Replacement Considerations
Other models in the ADR35xx family, such as ADR3530WBRMZ or ADR3550WBRMZ, offer different output voltages but maintain similar performance characteristics. Verify pin compatibility and thermal resistance specifications when substituting.
