INA126EA/2K5 General 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.
