Overview for Voltage Reference

TI’s broad portfolio of series, shunt, and current voltage references feature low temperature coefficient, precise initial accuracy, low noise, and excellent long term stability performance for a wide variety of applications such as in data conversion and signal conditioning. Voltage references are also commonly used as voltage monitors, current limiters, and programmable current sources.

Series voltage references

Additional feature capabilities such as low-Iq shutdown enable pin, noise-reduction/TRIM pin, and dual-output to achieve lower power consumption and higher precision.

Shunt voltage references

Fixed and adjustable references of various accuracy and voltage levels for systems requiring wide Vin and negative/floating references.

Current references

Floating dual and adjustable current source solutions for system protection and sensing.

Browse by key features
