Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Dual SPST Depletion Mode Audio Switch
Features
Description
The FSA551 is a high-performance dual single-pole
single-throw (SPST x 2) audio switch. The Depletion
Mode technology allows the device to conduct signals
when there is no VCC available and to isolate signals
when VCC is present. During signal conduction, the
Depletion Mode gate control allows the FSA551 to
achieve excellent THD+N performance while consuming
minimal power.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
