Fairchild FSA8008 audio jack detection and configuration switch

Fairchild Semiconductor developed the FSA8008 audio jack detection and configuration switch as a one-chip audio jack detector and switch for 3- or 4-pole accessories.

While current products use several discrete components (dual comparator, analog switch and MOSFET) with software control to meet this need, the FSA8008 integrates this functionality into a single device, simplifying designs, and saving up to 70 percent of the board space and up to 15 percent bill of material (BOM) costs , according to Fairchild.

Key highlights :

  • 15kV (air gap)
  • 12kV (HBM) ESD protection
  • 0.01 percent (typical) total harmonic distortion (MIC)
  • 10-lead UMLP package (1.4 x 1.8 x 0.5mm, 0.4mm pitch)


Pricing : (each, 1k pcs.):  FSA8008 = $0.33

Availability : Samples available now; delivery: 8-12 weeks ARO
