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.
