Product details

Single-channel instrumentation amp for precision sensor conditioning

The INA126E/250G4: Its 100 µV input offset and 10 nA input bias current suit bridge-type sensors, thermocouples, and load-cell front ends where the common-mode rejection matters more than raw bandwidth.

Speed-vs-power trade-off: 200 kHz bandwidth at 175 µA

The 200 kHz -3 dB bandwidth and 0.4 V/µs slew rate define the signal frequency the amplifier can faithfully reproduce. For a 10 Hz strain-gauge bridge or a 1 kHz thermocouple channel, this is ample headroom; for a 50 kHz ultrasound pulse, the slew rate will limit the output swing at higher gains. The 10 mA output drive per channel is sized for driving an ADC input or a twisted-pair cable run up to a few metres.

Frequently asked questions

Can the INA126E/250G4 be used in precision instrumentation?

Yes. The 100 µV input offset voltage and 10 nA input bias current make it suitable for precision sensor conditioning — bridge circuits, thermocouples, and load-cell amplifiers where the signal is a few millivolts and common-mode rejection is critical.
