UTC1062A - Low Voltage Telephone Transmission Circuit

General Description

The UTC1062A is a bipolar integrated circuit per- forming 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.

Key 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 (64k Ω for dynamic, magnetic or piezoelectric microphones.
  • Asymmetrical high-impedance inputs (32k Ω for electric microphones.
  • DTMF signal input with confidence tone.
  • Mute input for pulse or DTMF dialing.
  • Receiving amplifier for several t.

UTC1062A LI NEAR I NTEGRATED CI RCUI T LOW VOLTAGE TELEPHONE TRANSMISSION CIRCUIT WITH DIALLER INTERFACE DESCRIPTION The UTC1062A is a bipolar integrated circuit per- forming 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. FEATURES * Low d.c. line voltage; operates down to 1.
