Cirrus Logic is a fabless chip designer whose audio codecs, smart amplifiers and mixed-signal parts sit inside almost every iPhone — Apple is roughly 89% of its revenue. It designs in Austin and Edinburgh, has GlobalFoundries and TSMC build the chips, then Amkor/ASE package them — and is now pushing into laptops and power management to cut its Apple dependence.
