Versatile telephone transmission circuit with
dialler interface
The current Ip, available from VCC for supplying peripheral
circuits, depends on the external components and on the
line current. Fig.7 shows this current for VCC > 2.2 V and
for VCC > 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 VCC).
