UTC TEA1062N / TEA1062AN

LINEAR INTEGRATED CIRCUIT

LOW VOLTAGE TELEPHONE

TRANSMISSION CIRCUIT WITH

DIALLER INTERFACE

DESCRIPTION

integrated circuit performing all speech and line

interface function, required in the fully electronic

telephone

between

operate down to D.C. line voltage of 1.6V (with

reduced performance) to facilitate the use of more

telephone sets in parallel.

FEATURES

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

*Voltage regulator with adjustment static resistance.

*Provides supply with limited current for external

*Symmetrical high-impedance inputs (64k ) for
