TEA1069 - Versatile speech/dialler/ringer

Description

The TEA1069 and TEA1069A contain all the functions needed to build a highly featured, high-performance fully electronic telephone set.

The device incorporates a speech/transmission part, a dialler part and a ringer part.

Features

  • Speech part.
  • Voltage regulator with adjustable static resistance.
  • Low DC line voltage; operates down to 1.6 V (excluding polarity guard).
  • Supply for dialler part and peripherals (not stabilized).
  • Symmetrical high-impedance inputs (64 kΩ) for dynamic, magnetic, or piezoelectric microphones.
  • Asymmetrical high-impedance input (32 kΩ) for electret microphones.
  • Asymmetrical earpiece output for dynamic, magnetic, or piezoelectric earpieces.
