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

(RB 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.
