Product specification
Versatile telephone transmission circuit with
dialler interface
TEA1065
The current I
p
, available from V
CC
for supplying peripheral
circuits, depends on the external components and on the
line current. Fig.7 shows this current for V
CC
>
2.2 V and
for V
CC
>
3 V, where 3 V is the minimum supply voltage for
most CMOS circuits including a diode voltage drop for a
back-up diode. If MUTE is LOW the available current is
further reduced when the receiving amplifier is driven
(earpiece amplifier supplied from V
CC
).
