Description

LINEAR INTEGRATED CIRCUIT UNIVERSAL SPEECH CIRCUIT The UTC L6726 is a mask-programmable, monolithic integrated 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 200Ω, 48V,2 400Ω,and 36V,2 500Ω, can be handled.

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.
