REF3112AIDBZRG4

Overview

The REF3112AIDBZRG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.25 V with an initial accuracy of 0.2%. It operates within a supply voltage range up to 5.5 V and draws a typical quiescent current of 100 uA. The device features a temperature coefficient of 20 ppm/°C and supports a maximum shunt current of 10 mA. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides stable 1.25 V reference output with high initial accuracy
• Low power consumption suitable for battery-operated applications
• Compact three-pin SOT-23 package for space-constrained designs

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition channels

Procurement Notes

Verify the suffix RG4 indicates reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the specific grade matches design requirements for temperature stability. Check availability as distribution may vary by region.

Selection Notes

Select this component for applications demanding low noise and high stability in a small footprint. Compare against REF3112 variants if different packaging or shipping formats are required. Evaluate thermal performance within the specified operating range.

Part Context

This part belongs to the REF31xx family of low-power, high-precision voltage references. It shares architectural similarities with other members like the REF3112AIDBZT but differs in packaging configuration. The series is designed for general-purpose precision analog circuits.

Replacement Considerations

REF3112AIDBZT serves as a compatible alternative with identical electrical specifications but utilizes cut-tape packaging instead of reel format.
