INA126EA/250 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 (175 μA/channel). These features combined with a wide operating voltage range of ±1.35 V to ±18 V
make the INAx126 a great choice for portable instrumentation and data acquisition systems. Gain can be set from 5 V/V to 10000 V/V with a single external resistor. Precision input circuitry provides low
offset voltage (250 μV, maximum), low offset voltage drift (3 μV/°C, maximum), and excellent common-mode rejection. All versions are specified for the –40°C
to +85°C industrial temperature range.
