DESCRIPTION  
The UTC L6726 is  
a mask-programmable, monolithic  
integrated speech circuits for using in electronic telephones.  
It is designed for using with a low impedance microphone.  
Transmitting and receiving gain are regulated with line length.  
Different regulation for various current feeds can be set by  
external resistors. Typical current feeds as 48V 2·200, 48V,  
2·400, and 36V, 2·500, can be handled. Application  
dependent parameters such as line balance, side tone level,  
amplification and frequency response are set by external  
components. Parameters are set independently which means  
easy adaptation for various market needs.  
The UTC L6726 is developed for using with CMOS-type dialer  
ICs. A separate DTMF input is switched when the circuit is  
muted, and an adjustable DC supply is provided for feeding an  
external CMOS device.  
„
FEATURES  
*Minimum number of inexpensive external components, 5  
capacitors and 11 resistors.  
*Mute function for operation with DTMF-generator.  
*Transmit and receive gain regulation for automatic loop loss  
compensation.  
*Extended current and voltage range 5~130mA, down to 2V.  
*Differential microphone input for good balance to ground.  
*Balanced receiver output stage.  
*Short start-up time.  
*Stabilized DC-supply for low current CMOS dialers and/or  
electret microphones.  
*DTMF-input controlled by mute.
