DESCRIPTION
The INA115 is a low cost, general purpose instrumen-
tation amplifier offering excellent accuracy. Its versa-
tile three-op amp design and small size make it ideal
for a wide range of applications. Similar to the model
INA114, the INA115 provides additional connections
to the input op amps, A1 and A2, which improve gain
accuracy in high gains and are useful in forming
switched-gain amplifiers.
A single external resistor sets any gain from 1 to
10,000. Internal input protection can withstand up to
±40V without damage.
The INA115 is laser trimmed for very low offset
voltage (50µV), drift (0.25µV/˚C) and high common-
mode rejection (115dB at G=1000). It operates with
power supplies as low as ±2.25V, allowing use in
battery operated and single 5V supply systems. Quies-
cent current is 3mA maximum.
The INA115 is available in the SOL-16 surface-mount
package, specified for the –40°C to +85°C tempera-
ture range.

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.
