UTC L6726 LINEAR INTEGRATED CIRCUIT
UNIVERSAL SPEECH CIRCUIT
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

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
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.
