INA2126:Micropower Instrumentation Amplifier Single and Dual Versions

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 ?A/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-?V maximum), low offset voltage drift (3-?V/°C maximum), and excellent common-mode rejection.

Single version package options include 8-pin plastic PDIP, SOIC-8, and fine-pitch VSSOP-8 surface-mount. 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.
