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

matching the impedance at each input. The offset voltage error

caused by the input currents is decreased by more than an order

of magnitude.
