DRV8353: Amplifier output impedance R6 is confusing

Oskar Weigl1

Part Number: DRV8353

Hi, in the linked post it was revealed that R6 in the amplifier schematic is not actually present. This R6 is confusing and threw me off, and it would be nice if the datasheet can be updated.

I do have a related question: what is the input impedance (R1)?

Thanks.

Oskar,

R1 is 10k, R2 is 50k, R3, is 100k, R4 is 200k, R5 is 400k.

Great thank you! Perhaps a bit redundant, but I thought I'd mention it: please include this in the update also.
