APPLICATIONS
Offset Voltage Adjustment
The input offset voltage of the LT1001, and its drift with
temperature, are permanently trimmed at wafer test to a
low level. However, if further adjustment of Vos is neces-
sary, nulling with a 10k or 20k potentiometer will not
degrade drift with temperature. Trimming to a value other
than zero creates a drift of (Vos/300) V/ C, e.g., if Vos is

adjusted to 300 V, the change in drift will be 1 V/ C. The
adjustment range with a 10k or 20k pot is approximately
and resolution of the nulling can be improved by using a
smaller pot in conjunction with fixed resistors. The ex-
ample below has an approximate null range of 100 V.
The device under test should be warmed up for three
minutes and shielded from air currents.
