monitoring function.
DIFFERENCES BETWEEN TEA1096 AND TEA1096A
The TEA1096 offers via input VBA an adjustable stabilized
supply voltage V
BB
, whereas the TEA1096A offers a fixed
stabilized voltage V
BB
.
The TEA1096A offers a DC gain control input VCI to set
the loudspeaker volume, whereas the TEA1096 offers
volume control via a potentiometer.
GENERAL DESCRIPTION
The TEA1096 and TEA1096A are bipolar ICs intended for
use in line powered telephone sets. They offer a
speech/transmission function, listening-in and line
monitoring facilities of the received line signal via the
loudspeaker.
The devices incorporate a line interface block, a
microphone and DTMF amplifier, a receiving amplifier, a
supply function, a loudspeaker amplifier, and a dynamic
limiter in the transmission channel and the listening-in
channel.
