TPA3251: Slave Mode, DVDD and +3.3V source

Supira Medical
Intellectual 300 points
Part Number: TPA3251


Tool/software:

Hi,

The datasheet says that for slave mode, FREQ_ADJ should be connected to DVDD. However, the EVM connects it to an externally provided +3.3V source. Which is the correct way to do this?

A related question- can DVDD source enough current to pull up FREQ_ADJ, FAULT and CLIP or do I have to provide an external +3.3V?

Thanks.
