Product specification
One-chip telephone ICs with speech,
dialler and ringer functions
UBA2050(A); UBA2051(A;C)
Internal supply (pin V
CC
)
The internal transmission part circuitry is supplied from
V
CC
. This supply voltage is derived from the voltage on
pin LN by means of resistor R
CC
and must be decoupled
by capacitor C
VCC
connected between pins V
CC
and GND.
This supply point may also be used to supply peripheral
circuits e.g. an electret microphone taking into account the
supply possibilities according to Fig.8.
The voltage V
CC
(see Fig.9) depends on the current
consumed by the transmission part and the peripheral
circuits:
V
CC
= V
CC0
R
CC
×
(I
P
+ I
REC
)
where:
V
CC0
= V
LN
I
CC
×
R
CC
I
REC
= the current consumed by the output stage of the
earpiece amplifier.
