OFFSET TRIMMING  
voltage can be adjusted with the optional trim circuit con-  
nected to the Common pin as shown in Figure 2. The voltage  
applied to Common terminal is summed with the output.  
Low impedance must be maintained at this node to assure  
good common-mode rejection. The op amp connected as a  
buffer provides low impedance.  
The INA101 is laser trimmed for low offset voltage and  
drift. Most applications require no external offset adjust-  
ment. Figure 2 shows connection of an optional potentio-  
meter connected to the Offset Adjust pins for trimming the  
input offset voltage. (Pin numbers shown are for the DIP  
package.) Use this adjustment to null the offset voltage in  
high gain (G 100) with both inputs connected to ground.  
Do not use this adjustment to null offset produced by the  
source or other system offset since this will increase the  
offset voltage drift by 0.3µV/°C per 100µV of adjusted  
offset.  
THERMAL EFFECTS ON OFFSET VOLTAGE  
To achieve lowest offset voltage and drift, prevent air  
currents from circulating near the INA101. Rapid changes in  
temperature will produce a thermocouple effect on the  
package leads that will degrade offset voltage and drift. A  
shield or cover that prevents air currents from flowing near  
the INA101 will assure best performance.  
Offset of the output amplifier usually dominates when the  
INA101 is used in unity gain (G = 1). The output offset
