Apple Lightning to 30 Pin Adapter: Crus Audio 338S1081
Lightning Board Side 2
Here we have the bulk of the media devices. The Wolfson WM8533 DAC, that we think is taking the digital audio and converting it into the analog signal that the 30 pin delivers.
We also have the Apple 338S1081 which is a Cirrus Logic audio chip with die markings CLI1596A0 and date code 2011. For those who might be wondering as to its functionality, it didn’t directly compare to the die we cataloged in the prior generations of iPhones (in the models we tore down).
No surprise is that there are no similar chips here for converting video since there is no support for video out into the older 30-pin devices. This may impact some niche peripherals out there, but you can’t fight progress
