REF3312AIRSET

Overview

The REF3312AIRSET is a precision series voltage reference IC manufactured by Texas Instruments, housed in an 8-UQFN (1.5x1.5) package. It provides a fixed output voltage of 1.25 V with an initial accuracy of ±0.15%. The device features a temperature coefficient of 30 ppm/°C and operates within an input voltage range of 1.7 V to 5.5 V. Supply current is specified at 8.5 µA, while the maximum shunt current capability is 5 mA. It supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Series architecture providing stable voltage regulation
• High initial accuracy for precision applications
• Low power consumption suitable for battery-operated systems
• Wide operating temperature range for industrial environments

Applications

• Data acquisition systems requiring precise voltage references
• Industrial process control instrumentation
• Medical equipment with strict accuracy requirements
• Portable test and measurement devices

Procurement Notes

Verify the specific suffix 'SET' against the official Texas Instruments datasheet to confirm packaging configuration and reel specifications. Ensure the 8-UQFN package dimensions match the PCB footprint design. Cross-reference the RoHS compliance status with current environmental regulations. Confirm that the supply current and thermal characteristics align with the system's power budget and thermal management strategy before finalizing procurement.

Selection Notes

Select this component when a fixed 1.25 V reference with high initial accuracy is required. The low quiescent current makes it suitable for energy-constrained designs. Consider the 8-UQFN package size for space-limited applications. Evaluate the 30 ppm/°C drift against the system's long-term stability requirements. Ensure the input voltage range accommodates the available supply rails under all operating conditions.

Part Context

The REF3312AIRSET belongs to the REF3312 family of precision voltage references from Texas Instruments. This series is designed for applications demanding high accuracy and stability over temperature. The AIRSET variant indicates a specific tape-and-reel packaging option intended for automated surface-mount assembly processes, distinguishing it from cut-tape or tube configurations.
