0.1Hz to 10Hz Noise Test Circuit
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
±2.5mV.Iflessadjustmentrangeisneeded,thesensitivity
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.
