OFFSET VOLTAGE ADJUSTMENT
The offset voltage of the AD820 is low, so external offset voltage
nulling is not usually required. Figure 46 shows the recommended
technique for the AD820 packaged in plastic DIP. Adjusting offset
voltage in this manner changes the offset voltage temperature drift
by 4 μV/°C for every millivolt of induced offset. The null pins
are not functional for the AD820 in the 8-lead SOIC and MSOP
packages.
