Trying to identify a few components AudioTechnica ANC9
« on: February 20, 2016, 12:28:46 am »
Trying to repair a pair of noise cancelling headphones. Can anyone identify the two ICs in this picture:

They seemed to be made by National Semiconductor (or at least the logo looks that way), but I am not able to find any datasheets for these parts.
