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.MAX.12.0 10.0 30 20 1.4 +70 UNIT V V V Ω mA mA V mA °C ORDERING INFORMATION PACKAGE TYPE NU
