Notice
The circuits and measurements contained in this document are given only in the context of as examples of
applications for these products.
Moreover, these example application circuits are not intended for mass production, since the high-frequency
characteristics (the AC characteristics) of these devices will be affected by the external components which the
customer uses, by the design of the circuit and by various other conditions.
It is the responsibility of the customer to design external circuits which correctly implement the intended
application, and to check the characteristics of the design.
TOSHIBA assume no responsibility for the integrity of customer circuit designs or applications.
