3 Description
The INA126 and INA2126 (INAx126) are precision
instrumentation amplifiers for accurate, low-noise,
differential-signal acquisition. The two-op-amp design
provides excellent performance with low quiescent
current (175μA/channel). These features combined
with a wide operating voltage range of ±1.35V to
±18V make the INAx126 a great choice for portable
instrumentation and data acquisition systems.
Gain can be set from 5V/V to 10000V/V with
a single external resistor. Precision input circuitry
provides low offset voltage (250μV, maximum), low
offset voltage drift (3μV/°C, maximum), and excellent
common-mode rejection.
All versions are specified for the –40°C to +85°C
industrial temperature range.
