• Compact SC-70 surface-mount packaging for space-constrained designs
• High precision with ±0.2% initial accuracy and low temperature drift
• Two-terminal shunt configuration simplifies circuit implementation

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered systems where low static current is critical
• Data acquisition systems needing stable analog reference voltages

Procurement Notes

Verify the specific suffix (e.g., +T or +) to confirm lead-free compliance and RoHS status as indicated in official documentation. Ensure the ordering part number matches the required tolerance and package variant. Cross-reference with Analog Devices or authorized distributors for current availability and datasheet revisions.

Selection Notes

Select this component when a small form factor and high precision are required for shunt reference applications. Compare against series references if higher current drive or lower noise is needed. Verify that the SC-70 package thermal characteristics meet the application's power dissipation requirements under maximum operating conditions.
