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 (175A/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 (250V max), low offset voltage drift (3V/C max) and excellent common-mode rejection. Single version package options 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 40C to +85C industrial temperature range. V+
