GENERAL DESCRIPTION
The TEA1083/83A is a bipolar IC which has been
designed for use in line powered telephone sets. It is
intended to offer a monitoring facility of the line signal via
a loudspeaker during on-hook dialling. The TEA1083/83A
is intended for use in conjunction with a transmission
circuit of the TEA1060 family. The device uses a part of the
available line current via the internal supply circuit.
The loudspeaker amplifier, which consists of a preamplifier
and a power amplifier, amplifies the received line signals
from the transmission circuit when enabled via the LSE
input. The loudspeaker amplifier can also be used to
amplify dialling tones from the dialler IC. The power
amplifier contains a push-pull output stage to drive the
loudspeaker in a Single Ended Load (SEL) configuration.
The internal voltage stabilizer can be used to supply
external devices. By activating the power-down (PD) input
of the TEA1083A, the current consumption of the circuit
will be reduced, this enables pulse dialling or flash (register
recall).
An internal start circuit ensures normal start-up of the
transmission IC.
