Advance Information Programmable Telephone Line Interface Circuit with Loudspeaker Amplifier
The MC34216A is developed for use in telephone applications where, besides the standard telephone functions, the group listening- in feature is also required. In cooperation with a microcontroller, the circuit performs all basic telephone functions including DTMF generation and pulse- dialing. The listening- in part includes a loudspeaker amplifier, an anti- howling circuit and a strong supply. In bination with the TCA3385, the ringing is performed via the loudspeaker.
