The input resistance at pin 1 depends on the threshold voltage V

R1 =
Referring to the following input stage, the possible attenuation of the input signal and therefore of the output
signal can be found using the following expression.
Considering Rg = 10 K
muting-on condition is typically A
muting-off condition, the attenuation is very low,
typically 1.2 dB.
A very low current is necessary to drive the thresh-
old voltage V
11 is greater than 150 K . The muting function can
be used in many cases, when a temporary inhibition
of the output signal is requested, for example:
- in switch-on condition, to avoid preamplifier
power-on transients (see fig. 27)

The variable impedance capability at pin 1 can be
useful in many applications and we have shown 2
examples in fig. 22 and 24, where it has been used
to change the feedback network, obtaining 2 differ-
ent frequency responses.
