REF3140AIDBZRG4

Overview

The REF3140AIDBZRG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 4.096 V. It features an initial accuracy of 0.2% and a low temperature coefficient of 20 ppm/°C. The device operates with a supply current of 100 µA and supports a maximum input voltage of 5.5 V. It functions within a junction temperature range of -40°C to +125°C and provides a maximum shunt current of 10 mA. Packaged in a compact SOT-23-3 surface-mount case, it is designed for high-stability applications requiring minimal power consumption.

Feature Summary

Provides stable 4.096 V reference with 0.2% initial accuracy
Low temperature drift of 20 ppm/°C ensures thermal stability
Ultra-low quiescent current of 100 µA optimizes battery life
Compact SOT-23-3 package suitable for space-constrained designs

Applications

Portable instrumentation systems
Battery-powered measurement devices
Data acquisition systems
Precision analog front ends

Procurement Notes

Verify the complete part number including the TG4 suffix to ensure correct packaging and RoHS compliance. Confirm availability status as lifecycle changes may affect long-term supply. Cross-reference specifications against the official datasheet to validate performance requirements for your specific application environment.

Selection Notes

Select this component when high precision and low power are critical. The 20 ppm/°C coefficient offers superior thermal stability compared to standard references. Ensure input voltage remains within the 5.5 V limit. Consider the 10 mA load capability for driving downstream circuitry without external buffering.

Part Context

Part of the REF31xx family, this device targets applications demanding higher precision than the REF29xx series. It shares the SOT-23-3 footprint but improves upon temperature coefficients and initial accuracy. It serves as a drop-in replacement for legacy references requiring tighter tolerance specifications in compact form factors.
