TEA1081 Datasheet - NXP

TEA1081 telephone set peripherals power-down

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-.

* 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
