TEA1081 Datasheet Telephone Set Peripherals Power-down

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TEA1081 Supply circuit with power-down for telephone set peripherals Product specification Supersedes data of February 1988 File under Integrated Circuits, IC03 September 1994 Philips.

General Description

TEA1081 The TEA1081 is an integrated circuit for use in line-powered telephone sets to supply peripheral circuits for extended dialling and/or loudspeaker facilities.

The IC uses a part of the surplus line current normally drawn by the voltage regulator of the speech/transmission circuit.

A power-down function isolates the IC from its load and reduces the input current.

Key Features

  • High input impedance for audio signals.
  • Low DC series resistance.
  • High output current.
  • Large audio signal handling capability.
  • Low distortion.
  • Two modes of operation:.
  • output voltage that follows the DC line voltage.
  • regulated output voltage.
  • Power-down input.
  • Low number of external components. QUICK.
