Hello,
I have a circuit that uses a MT8880C to create DTMF tones. I want to
interface this with the telephone system - to do this I'll need a DAA
chip, right??
I don't need any fancy features - just the ability to transmit analog
frequencies ( the tones I'm dialing on the MT8880) and some way to
pick up / hang up the phone. Can anyone suggest a simple, cheap DAA??
