MUTINGFUNCTION
The output signal can be inhibited applying a DC voltageV
T
to pin 11,as shown in fig. 28

Considering Rg = 10 K
the attenuation in the
muting-on condition is typically A
T
= 60 dB. In the
muting-off condition, the attenuation is very low,
typically 1.2 dB.
Avery low current is necessaryto drivethe thresh-
old voltage V
T
becausethe input resistance at pin
11is greaterthan150 K
. Themutingfunction can
beusedinmanycases,whenatemporaryinhibition
of the output signal is requested,for example:
- in switch-on condition, to avoid preamplifier
power-on transients (see fig. 27)
- during commutationsat the input stages.
- during the receivertuning.
The variable impedancecapability at pin 1 can be
useful in many applications and we have shown 2
examplesin fig.22 and24, where it hasbeen used
to changethe feedbacknetwork,obtaining2 differ-
ent frequency responses.
