While the official purpose of this IC is unknown, at minimum we can guess that it contains a digital-to-analog converter (DAC) and amplifier, and its counterpart, an analog-to-digital-converter (ADC). Thanks to longtime iFixit community member OldTurkey03 for his teardown of the audio adapter. He uncovered that mystery IC by the Lightning connector, marked 338S00140 A0SM1624 TW-which doesn’t tell us much, other than it’s an Apple part number.
