DG2592 Audio Jack Detector and DG2750 Analog Switch

Vishay’s DG2592 and DG2750 are offered in a space-saving miniQFN10 package with ultra-thin 0.35 mm profile for use in portable applications

Image of Vishay's DG2592 and DG2750 Audio Jack Detector and Analog SwitchVishay introduces a 1.4 mm x 1.8 mm miniQFN10 package with an ultra-thin 0.35 mm profile, providing a space-saving alternative to larger miniQFN10 and WCSP devices commonly used in portable applications. The Vishay Siliconix DG2592 audio jack detector and DG2750 low-voltage dual SPDT analog switch are the first devices in the family of solutions to feature the enhanced package.

  • Enhanced package is 36% thinner than typical miniQFN10 and WCSP packages, saving valuable PCB space and allowing for slimmer end products
  • Compared to WCSP packages, the enhanced miniQFN10 offers easier surface mounting and is better suited for flexible PCBs commonly utilized in portable designs
  • DG2592 features integrated circuits for detecting the presence of a stereo headset with a microphone and send / end control button
  • DG2750 is capable of switching negative swing audio without the need for a coupling capacitor
