UTC MC33218 LINEAR INTEGRATED CIRCUIT  
VOICE SWITCHED  
SPEAKERPHONE WITH  
MICROPROCESSOR INTERFACE  
DESCRIPTION  
The UTC MC33218 voice switched speakerphone circuit  
incorporates the necessary amplifiers, attenuators, level  
detectors and control algorithm to form the heart of a high  
quality hands-free speaker-phone system. Includes are a  
microphone amplifier with mute, transmit and receive  
attenuators a background monitoring system for both the  
transmit and receive paths, and level detectors for each path.  
An AGC system reduces the receive gain on long lines where  
loop current and power are in short supply. A dial tone  
detector prevents fading of dial tone. A chip disable pin  
permits conserving power when the circuit is not in use.  
Additionally, the UTC MC33218 has a serial data port  
which permits microprocessor control of the receive volume  
level, microphone mute, attenuator range, and selection of  
transmit, receive, idle or normal modes. The data port can be  
operated at up to 1.0MHz  
SOP-24  
DIP-24  
The UTC MC33218 can be operated from a power supply,  
or from the telephone line, requiring typically 4.6mA.It can be  
used in conjunction with a variety of speech networks.  
Applications include not only speakerphones, but intercoms  
and other voice switched devices.  
FEATURES  
* Supply Voltage Range: 2.7V ~ 6.5V  
* Attenuator Range: 53 or 27 dB (selectable)  
* 2 Point Sensing with background oise monitor in each path  
* Microprocessor port for control of:  
Volume control(40dB range over 16 levels)  
Mute microphone amplifier  
Force to receive transmit, or idle modes  
Attenuator range selection(27 or 53dB)
