MICROPOWER INSTRUMENTATION AMPLIFIER

The INA126 and INA2126 are precision instrumentation amplifiers for accurate, low noise differential signal acquisition. Their
two-op-amp design provides excellent performance with very low quiescent current (175µA/channel). This, combined with a
wide operating voltage range of ±1.35V to ±18V, makes them ideal for portable instrumentation and data acquisition systems.
Gain can be set from 5V/V to 10000V/V with a single external resistor. Laser trimmed input circuitry provides low offset voltage (250µV max), low offset voltage drift (3µV/°C max) and excellent common-mode rejection.
