Other Parts Discussed in Thread: TAS6424
We are using the AC Diagnostics features to measure speaker characteristics. Pasted below is a screen capture of the formulae taken from one of the TI training videos.
We are measuring impedance by reading each of the registers from 0x17 to 0x1a and multiplying by 0.2496 since that is suggested by the datasheet. However, the screen capture below shows a multiplier of 2.37. Why the difference? Could you please clarify how to measure impedance?
Secondly, we don't understand how to measure phase. How do the parameters shown in the formula relate to the register values read from addresses 0x1b to 0x1e. Also, do the specific capacitors or inductors that we have chosen to use as part of the TAS6424 circuit somehow impact the calculation? Could someone please help us figure out how to measure phase?
Thank in advance for the help!
