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
B
in Figures 1 and 2) be used to reduce bias current errors by
matching the impedance at each input. The offset voltage error
caused by the input currents is decreased by more than an order
of magnitude.
