9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The REF54 is designed for the applications where high precision is required at lower power. Low temperature

drift and noise makes the REF54 excellent attach for high precision data converters to achieve best gain drift

and resolution.
