In terms of the measured output peak-to-peak noise, the
following relationship holds between output noise voltage, e
n
p-p, for different closed-loop gain, A
V
, settings, where 3 dB
Bandwidth is BW:
It should be kept in mind that in order to minimize the output
noise voltage for a given closed-loop gain setting, one could
minimize the overall bandwidth. As can be seen from Equa-
tion 1 above, the output noise has a square-root relationship
to the Bandwidth.
In the case of the inverting configuration, it is also possible to
increase the input impedance of the overall amplifier, by
raising the value of R1, without having to increase the feed-
back resistor, R2, to impractical values, by utilizing a "Tee"
network as feedback. See the LMC6442 data sheet (Appli-
cation Notes section) for more details on this.
