Title: How rds is defined in H-bridge class-d Amp?
Post by dandelion on Feb 27th, 2008, 7:00pm

Hi,
pls. take a look at the attached PDF file. It is the datasheet of the class-d amplifier from TI.

I have one puzzles on the page 3, the electrical characteristics table, the yellow part. It defined the Rds(on), the static drain-source on resistance.

It should be the adding of the rds of PMOS and NMOS power Tr. So I wonder how it is measured or how it is simulaed in the design?

Pls. help.

Thanks
