One for the GURU's....
Hi chaps, TA2024 Tripath chips.... or any tripath chip for that matter.... No please, don't go away... please read on..
 The chips put their internal reference voltage to ground via a 8.25K resistor.... Can someone explain what the purpose of this is please? I just wondered if it contributes to the DC offset you get on these chips....? Thanks for any 'Bias'ed' input you can give... sorry couldn't resist Lee The datasheet |

It could be a dummy load to bias the internal regulator in absence of other loads.
It could be also a way to draw a current value within a particular range. This condition may be detected internally and used to turn on or off some feature.
