TS3A44159: Any part support negative voltage?

Part Number: TS3A44159

Hi,

Hi,

Customer now uses two TS3A44159 for analog audio signal as shown below in the original circuit.  Now, for the purpose to reduce the pulse which cause pop-noise, they add an AC couple cap at the left TS3A44159 chip (see modified circuit.)  But now, there's a side effect from this added AC couple cap: The output of the TS3A44159 at right side was clipped for the negative component.

The question here is,

  • Do we have any part corresponding to TS3A44159 which support negative voltage?  (I can't find it.)

Thanks!

Antony
