The VIN pin used
as signal input
2082 – 17
This connection is useful when a high input impedance is required There are a few caveats when using
the VIN pin The first is that VIN has a 250 V ms slew rate limitation The second is that the inevitable
CSTRAY across Rg causes a gain zero and gain INCREASES above the 1(2q CSTRAY Rg) frequency
and can peak as much as 20 dB with large CSTRAY A graph of gain vs frequency for several CSTRAYS
is included in the typical performance curves In general if wide bandwidth and frequency flatness is
desired the IIN pin should be used
The VIN pin does make an excellent ground reference pin for instance when low-frequency noise is to
be rejected The next schematic shows the EL2082 VIN pin rejecting possible 60 Hz hum induced on an
RF input cable
Using the VIN pin
as a ground reference
to reject hum and noise
2082 – 18
This example shows VIN rejecting low-frequency field-induced noise but not adding peaking since the
001
mF bypass capacitor shunts high-frequency signals to local ground
