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, A
1
and A
2
, 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 (50
μ
V), drift (0.25
μ
V/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.
