INPUT STAGE
The TDA7382’S inputs are ground-compatible
and can stand very high input signals (
±
8Vpk)
without any performancesdegradation.
If the standard value for the input capacitors
(0.1
μ
F) is adopted, the low frequency cut-off will
amount to 16 Hz.
STAND-BY AND MUTING
STAND-BY and MUTING facilities are both
CMOS-COMPATIBLE. If unused, a straight con-
nection to Vs of theirrespectivepins would be ad-
missible. Conventionallow-power transistors can
be employed to drive muting and stand-by pins in
absence of true CMOS ports or microprocessors.
R-C cells have always to be used in order to
smooth down the transitions for preventing any
audibletransient noises.
Since a DC current of about 10 uA normallyflows
out of pin 22, the maximum allowable muting-se-
ries resistance (R
2
) is 70K
, which is sufficiently
high to permit a muting capacitor reasonably
small(about 1
μ
F).
If R
2
is higher than recommended, the involved
risk will be that the voltage at pin 22 may rise to
above the 1.5 V threshold voltage and the device
will consequently fail to turn OFF when the mute
line is broughtdown.
