When you consider any use or application of these products, please make inquiries the sales office
of Asahi Kasei Microdevices Corporation (AKM) or authorized distributors as to current status of the
products.
 Descriptions of external circuits, application circuits, software and other related information
contained in this document are provided only to illustrate the operation and application examples of
the semiconductor products. You are fully responsible for the incorporation of these external circuits,
application circuits, software and other related information in the design of your equipments. AKM
