The accuracy and temperature drift of the R
G
resistors
also influence the IC’s precision and gain drift, and can
be derived from the equation above. With low R
G
val-
ues, which are required for high-gain operation, para-
sitic resistances may significantly increase the gain
error.
Capac itive Load S tability
The MAX4194–MAX4197 are stable for capacitive loads
up to 300pF (Figure 6a). Applications that require
greater capacitive-load driving capability can use an
isolation resistor (Figure 6b) between the output and
the capacitive load to reduce ringing on the output sig-
nal. However, this alternative reduces gain accuracy
because R
ISO
(Figure 6c) forms a potential divider with
the load resistor.
