MC34216規(guī)格書(shū)詳情
Programmable Telephone Line Interface Circuit with Loudspeaker Amplifier
The MC34216 is developed for use in telephone applications where besides the standard telephone functions also the group listening–in feature is 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.
