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.
- 15kV (air gap)
- 12kV (HBM) ESD protection
- 0.01 percent (typical) total harmonic distortion (MIC)
