LT1001
0.1Hz to 10Hz Noise Test Circuit
Offset Voltage Adjustment
The input offset voltage of the LT1001, and its drift with tempera-
ture, are permanently trimmed at wafer test to a low level.
However, if further adjustment of Vos is necessary, nulling with
a 10k or 20k potentiometer will not degrade drift with tempera-
ture. Trimming to a value other than zero creates a drift of (Vos/
300)
μ
V/
°
C, e.g., if Vos is adjusted to 300
μ
V, the change in drift
will be 1
μ
V/
°
C. The adjustment range with a 10k or 20k pot is
approximately
±
2.5mV. If less adjustment range is needed, the
sensitivity and resolution of the nulling can be improved by using
a smaller pot in conjunction with fixed resistors. The example
below has an approximate null range of
±
100
μ
V.
