Package Drawing:

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 mimmal power.
