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 (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.
