#8827 - RE: Help for MT8880 dialer IC:
Hi,

I have resolved the problem by changing the input configuration from single ended to the differential type input.

This has increased the gain and minimized the signal loss as it is now without the transformer. The transformer was eating away a great part of the signal.

Now it can detect the DTMF tones from the remote caller.

Thank you

Simon
