UTCTEA1062N - LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE

Datasheet Summary

Description

The UTC TEA1062N / TEA1062AN is a bipolar integrated circuit performing 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.

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.
  • Asymmetrical high-impedance inputs (32kΩ) for electret microphones.
  • DTMF signal input with confidence tone.
  • Mute input for pulse or DTMF dialing.
  • Receivering amplifier for several.

UTC TEA1062N / TEA1062AN LINEAR INTEGRATED CIRCUIT LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE DESCRIPTION The UTC TEA1062N / TEA1062AN is a bipolar integrated circuit performing 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. SOP-16 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.
