TI INA126EA/2K5

The INA126 and INA2126 are precision instrumentation amplifiers for accurate, low noise differential-signal acquisition. Their two-op-amp design provides excellent performance with low quiescent current (175 μA/channel). Combined with a wide operating voltage range of ±1.35 V to ±18 V, makes the INAx126 ideal for portable instrumentation and data acquisition systems. Gain can be set from 5 V/V to 10000 V/V with a single external resistor. Laser-trimmed input circuitry provides low offset voltage (250 μV maximum), low offset voltage drift (3 μV/°C maximum), and excellent common-mode rejection. Single version package options include 8-pin plastic PDIP, SOIC-8, and fine-pitch VSSOP-8 surfacemount. Dual version is available in 16-pin plastic PDIP, SOIC-8, and the space-saving, fine-pitch SSOP-16 surface-mount. All are specified for the -40°C to +85°C industrial temperature range.
