TEA1081
Information as of 2000-08-22
TEA1081; Supply circuit with power-down for telephone set peripherals
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.
l
High input impedance for audio signals
l
Low DC series resistance
l
High output current
l
Large audio signal handling capability
l
Low distortion
l
Two modes of operation:
- output voltage that follows the DC line voltage
- regulated output voltage
l
Power-down input
l
Low number of external components.
