TEA1064A - Low voltage versatile telephone transmission

Description

The TEA1064A is a bipolar integrated circuit that performs all the speech and line interface functions required in fully electronic telephone sets.

It performs electronic switching between dialling and speech and has a powerful DC supply for peripheral circuits.

Features

  • Low DC line voltage; operates down to 1.8 V (excluding polarity guard).
  • Voltage regulator with low voltage drop and adjustable static resistance.
  • DC line voltage adjustment facility.
  • Provides a supply for external circuits in two options: unregulated supply, regulated line voltage; stabilized supply, line voltage varies with supply current.
  • Dynamic limiting (speech-controlled) in transmit direction prevents distortion of line signal and sidetone.
