Description  
The telephone circuit U4089B-M is a linear integrated circuit for use in feature phones,  
answering machines and fax machines. It contains the speech circuit, side tone  
equivalent and ear protection rectifiers. The circuit is line-powered and contains all  
components necessary for the amplification of signals and adaptation to the line.  
An integrated voice switch with a loudspeaker amplifier enables loud-hearing or  
hands-free operation. With an anti-feedback function, acoustical feedback during loud-  
hearing can be reduced significantly. The generated supply voltage is suitable for a  
wide range of peripheral circuits.
