Overview

Order this document by MC33215/D MC33215 Advance Information Telephone Line Interface and Speakerphone Circuit The MC33215 is developed for use in fully electronic telephone sets with speakerphone functions.
The circuit performs the ac and dc line termination, 2–4 wire conversion, line length AGC and DTMF transmission.
The speakerphone part includes a half duplex controller with signal and noise monitoring, base microphone and loudspeaker amplifiers and an efficient supply.
The circuit is designed to operate at low line currents down to 4.
0 mA enabling parallel operation with a classical telephone set.
