onsemi FSA553 Dual SPST Depletion Mode Audio Switch
onsemi FSA553 dual SPST depletion-mode audio switches allow the IC to conduct signals when there is no VCC available and to isolate signals when VCC is present. During signal conduction, the depletion gate control allows the onsemi FSA553 to achieve excellent THD+N performance while consuming minimal power.
