TELEPHONE LINE

INTERFACE CIRCUIT WITH

LOUDSPEAKER AMPLIFIER

SEMICONDUCTOR

TECHNICAL DATA

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 combination with the TCA3385, the ringing is

performed via the loudspeaker.
