DESCRIPTION
The INA126 and INA2126 are precision instrumentation
amplifiers for accurate, low noise differential signal acquisi-
tion. Their two-op-amp design provides excellent perfor-
mance with very low quiescent current (175
μ
A/chan.). This,
combined with wide operating voltage range of
±
1.35V to
±
18V, makes them ideal for portable instrumentation and data
acquisition systems.
Gain can be set from 5V/V to 10000V/V with a single
external resistor. Laser trimmed input circuitry provides
low offset voltage (250
μ
V max), low offset voltage drift
(3
μ
V/
°
C max) and excellent common-mode rejection.
Single version package options include 8-pin plastic DIP,
SO-8 surface mount, and fine-pitch MSOP-8 surface-mount.
Dual version is available in the space-saving SSOP-16 fine-
pitch surface mount, SO-16, and 16-pin DIP. All are speci-
fied for the –40
°
C to +85
°
C industrial temperature range.
