GENERAL DESCRIPTION
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.

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.
