ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user’s own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
any BURR-BROWN product for use in life support devices and/or systems.

OFFSET TRIMMING
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.
Offset of the output amplifier usually dominates when the
INA101 is used in unity gain (G = 1). The output offset
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.
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.
