PROGRAMMABLE TELEPHONE LINE INTERFACE CIRCUIT WITH LOUDSPEAKER AMPLIFIER
ORDERING INFORMATION
Order this document by MC34216A/D-- ! -
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. Programmable DC Mask, for France, U.K., and Voltage Regulated
Countries DC Mask for France and U.K. (MC34216ADWF) Programmable Volume for Listening–In and Ringing Small Amount of External Components On–Chip DTMF and Ring Signal Generator Efficient Supply Point for Loudspeaker Amplifier and Peripherals Programmable Modes for Speakerphone, Answering Machine, Fax and
Modem Applications Pilot and Idle Tones Provide Extra Phone Features
