OFFSET NULLING
The THS403x has very low input offset voltage for a high speed amplifier. However, if additional correction is
required, the designer can make use of an offset nulling function provided on the THS4031. By placing a
potentiometer between terminals 1 and 8 of the device and tying the wiper to the negative supply, the input offset
can be adjusted. This is shown in Figure 56.
Figure 56. Offset Nulling Schematic
OFFSET VOLTAGE
The output offset voltage (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) times
the corresponding gains. The following schematic and formula can be used to calculate the output offset voltage:
