DESCRIPTION
The INA326 and INA327 (with shutdown) are high-perfor-
mance, low-cost, precision instrumentation amplifiers with
rail-to-rail input and output. They are true single-supply
instrumentation amplifiers with very low DC errors and input
common-mode ranges that extends beyond the positive and
negative rails. These features make them suitable for appli-
cations ranging from general-purpose to high-accuracy.
Excellent long-term stability and very low 1/f noise assure
low offset voltage and drift throughout the life of the product.
The INA326 (without shutdown) comes in the MSOP-8 pack-
age. The INA327 (with shutdown) is offered in an MSOP-10.
Both are specified over the industrial temperature range,
–40°C to +85°C, with operation from –40°C to +125°C.

ABSOLUTE MAXIMUM RATINGS(1)
Supply Voltage .................................................................................. +5.5V
Signal Input Terminals: Voltage(2) .............................. 0.5V to (V+) + 0.5V
Current(2) ................................................... ±10mA
Output Short-Circuit ................................................................. Continuous
Operating Temperature Range ....................................... 40°C to +125°C
Storage Temperature Range .......................................... 65°C to +150°C
Junction Temperature .................................................................... +150°C
Lead Temperature (soldering, 10s) ............................................... +300°C
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. These are stress ratings only, and functional operation of the
device at these or any other conditions beyond those specified is not implied.
(2) Input terminals are diode clamped to the power-supply rails. Input signals that
can swing more than 0.5V beyond the supply rails should be current limited to
10mA or less.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion 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.
