Product Summary

The INA126UA is a precision instrumentation amplifier 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 of the INA126UA provides low offset voltage (250μV max), low offset voltage drift (3μV/℃ max) and excellent common-mode rejection. Single version package options of the INA126UA include 8-pin plastic DIP, SO-8 surface mount, and fine-pitch MSOP-8 surface-mount. Dual version is available in the space-saving SSOP-16 finepitch surface mount, SO-16, and 16-pin DIP. All are specified for the –40℃ to +85℃ industrial temperature range.
