The INA126 and INA2126 are precision instrumentation amplifiers for accurate, low noise
differential-signal acquisition. Their two-op-amp design provides excellent performance with low
quiescent current (175 µA/channel). Combined with a wide operating voltage range of ±1.35 V to ±18
V, makes the INAx126 ideal for portable instrumentation and data acquisition systems.
Gain can be set from 5 V/V to 10000 V/V with a single external resistor. Laser-trimmed
input circuitry provides low offset voltage (250-µV maximum), low offset voltage drift (3-µV/°C
maximum), and excellent common-mode rejection.
Single version package options include 8-pin plastic PDIP, SOIC-8, and fine-pitch VSSOP-8
surface-mount. Dual version is available in 16-pin plastic PDIP, SOIC-8, and the space-saving,
fine-pitch SSOP-16 surface-mount. All are specified for the –40°C to +85°C industrial temperature
