Product details

Single-channel instrumentation amp — 175 µA supply, 200 kHz bandwidth

It draws 175 µA supply current while delivering a 200 kHz -3 dB bandwidth and a 0.4 V/µs slew rate. The 100 µV input offset and 10 nA input bias current suit bridge sensors, thermocouple front-ends, and medical instrumentation where the common-mode rejection matters more than raw speed.

The supply range spans 2.7 V to 36 V, so the same part works off a single lithium cell or a 24 V industrial bus.

The base product number INA126 shares the same die and pinout across the family; the E/2K5G4 suffix specifies the 8-VSSOP package on a 2,500-unit Tape & Reel.

Frequently asked questions

Is INA126E/2K5G4 a replacement for INA126?

Yes. INA126E/2K5G4 is a specific ordering variant of the base INA126 instrumentation amplifier. The base product number is INA126, and this variant adds the 8-VSSOP package and Tape & Reel packaging. The electrical specifications — 0.4 V/µs slew rate, 200 kHz bandwidth, 175 µA supply current — are identical across the INA126 family.

Can INA126E/2K5G4 be used in battery-powered applications?

Yes. The 175 µA supply current and the 2.7 V minimum supply voltage make it suitable for battery-powered instrumentation. The 0.4 V/µs slew rate is adequate for low-frequency sensor signals such as strain gauges, thermocouples, and pressure transducers where the bandwidth stays well below 200 kHz.
