Overview
The ADR512WARTZ-R7 is a precision shunt voltage reference providing a nominal output of 1.2 V in an ultracompact 3-lead SOT-23 package. It features an initial accuracy of ±0.67% maximum and a temperature coefficient of 60 ppm/°C. The device operates within a current range of 100 µA to 10 mA and exhibits low output noise of 4 µV p-p from 0.1 Hz to 10 Hz. Qualified for automotive applications, it functions reliably across a temperature range of −40°C to +85°C.
Feature Summary
- Ultracompact 3-lead SOT-23 package designed for space-critical applications
- Advanced design eliminates the need for external capacitors while maintaining stability with any capacitive load
- TRIM terminal allows adjustment of output voltage over ±0.5% without affecting temperature coefficient
Applications
- Automotive systems
- Precision data acquisition systems
- Microcontroller reference voltage
Procurement Notes
Verify that the specific part number suffix matches the required automotive qualification and RoHS compliance status. Confirm the package option corresponds to the 3-Lead SOT-23 form factor. Ensure the ordering quantity aligns with the standard reel size of 3,000 parts per reel as specified in the manufacturer's ordering guide.
Selection Notes
Select this component when a stable 1.2 V reference is required in minimal footprint designs. The absence of external capacitor requirements simplifies circuit layout. Consider the TRIM pin if system-level calibration is necessary to compensate for board-level errors without degrading thermal performance.
Part Context
This device belongs to the ADR512 series of precision voltage references manufactured by Analog Devices. It is specifically engineered for applications demanding high accuracy and low noise in compact environments. The automotive-grade variant ensures reliability under stringent quality and environmental standards typical of vehicle electronics.
Replacement Considerations
