OFFSET NULLING
The input voltage of the AD848 and AD849 are very low for
high speed op amps, but if additional nulling is required, the
circuit shown in Figure 3 can be used.
For high performance circuits it is recommended that a resistor
(R
in Figures 1 and 2) be used to reduce bias current errors by
B
matching the impedance at each input. The offset voltage error
caused by the input currents is decreased by more than an order
of magnitude.
