               Letter Regarding Arthur Andersen Representations

[SEMTECH LETTERHEAD]


To the Securities and Exchange Commission:

     We received a letter from Arthur Andersen LLP, dated April 2, 2002,
representing that the audit as of and for the year ended January 27, 2002, was
subject to their quality control system for the U.S. accounting and auditing
practice to provide reasonable assurance that the engagement was conducted in
compliance with professional standards, that there was appropriate continuity of
Arthur Andersen personnel working on the audit and availability of national
office consultation, and availability of personnel at foreign affiliates of
Arthur Andersen to conduct the relevant portions of the audit.

Very truly yours,

/S/ David G. Franz Jr.
