DRV135: Unbalance signal

Genius 17545 points
Part Number: DRV135
Other Parts Discussed in Thread: DRV134,

Hi Experts,

This question is regarding the DRV135UA.

We have a product using this chip and we're designing the manufacturing tests.
Can the cold side be safely connected to ground to create a unbalanced signal? Our current audio testing solutions uses unbalanced inputs.

Regards,
Archie A.

  • Hi Archie,

    I believe section 8.4.2 of the DRV134/135 datasheet covers this topic.

    DRV134 is shown in the figure, but this configuration is valid for the DRV135 as well.

    Thanks,
