INA126/INA2126 pdf datasheet (

The INA126 and INA2126 are precision instrumentation
amplifiers for accurate, low noise differential signal acquisition.
Their two-op-amp design provides excellent performance
with very low quiescent current (175mA/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 (250mV max), low offset voltage drift
(3mV/°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 finepitch
surface mount, SO-16, and 16-pin DIP. All are specified
for the –40°C to +85°C industrial temperature range.
