LINEAR INTEGRATED CIRCUIT

LOW VOLTAGE TELEPHONE

TRANSMISSION CIRCUIT

WITH DIALLER INTERFACE

DESCRIPTION

The UTC1062 is a bipolar integrated circuit per-

forming all speech and line interface function required

in the fully electronic telephone sets. It performs

electronic switching between dialing speech. The

circuit is able to operate down to d.c. line voltage of

1.6v (with reduced performance) to facilitate the use

of more telephone sets in parallel.

DIP-16

FEATURES

* Low d.c. line voltage; operates down to 1.6V

SOP-16

(excluding polarity guard)

* Voltage regulator with adjustment static resistance

* Provides supply with limited current for external

circuitry

* Symmetrical high-impedance inputs (64kΩ for

dynamic, magnetic or piezoelectric microphones

* Asymmetrical high-impedance inputs (32kΩ for

electric microphones

* Receiving amplifier for several types of earphones

* Large amplification setting range on microphone

and ear piece amplifiers

* Line loss compensation facility , line current

dependent (microphone and ear piece amplifiers)

* Gain control adaptable to exchange supply

* Possibility to adjust the d.c. line voltage

* DTMF signal input with confidence tone

* Mute input for pulse or DTMF dialing
