UTC TEA1062/1062A LINEAR INTEGRATED CIRCUIT LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE DESCRIPTION The UTC TEA1062/1062A is a bipolar integrated circuit performing all speech and line interface function, telephone between required dialing in the fully electronic sets. It performs electronic switching speech. The circuit is able to SOP-16 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 (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.
