THS6222RHF Evaluation Module

This user's guide describes the characteristics, operation, and use of the THS6222RHFEVM. This
evaluation module (EVM) is an evaluation and development kit for evaluating the THS6222IRHF, a
differential line-driver amplifier with a current-feedback architecture that is targeted for use in broadband
power line communications (PLC) line driver applications. A complete circuit description as well as
schematic diagram and bill of materials are included in this document.

Throughout this document, the abbreviation

EVM

and the term

evaluation module

are synonymous with
