MOTOROLA ANALOG IC DEVICE DATA
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.
Highly Integrated Cost Effective Solution
Straightforward AC and DC Parameter Adjustments
Efficient Supply for Loudspeaker Amplifier and Peripherals
Stabilized Supply Point for Handset Microphone
Stabilized Supply Point for Base Microphone
Loudspeaker Amplifier can be Powered and Used Separately
Smooth Switch–Over from Handset to Speakerphone Operation
Adjustable Switching Depth for Handsfree Operation
Simplified Application
This device contains 2782 active transistors.
