Texas Instruments INA2126
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.| Part No. | INA2126 |

DESCRIPTION
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.
