What are the key features of INA597IDT?

  • 200 µV maximum input offset voltage with e-trim precision ensures accurate differential signal measurement in industrial instrumentation
  • 88 dB minimum CMRR (90 dB typical) rejects common-mode noise for reliable signal extraction in noisy environments
  • 2 MHz bandwidth with low-power voltage-feedback architecture supports high-fidelity signal amplification in battery-sensitive designs

What is INA597IDT used for?

INA597IDT is designed for precision differential signal conditioning in industrial current sensing, bridge amplifiers, and data acquisition systems requiring low offset and high common-mode rejection. Its 88 dB CMRR and 200 µV offset specification make it well-suited for strain gauge signal chains, thermocouple amplifiers, and medical monitoring equipment where small differential voltages must be accurately extracted from large common-mode levels. The 8-SOIC package provides easy PCB integration in instrumentation amplifier front ends and motor-drive current feedback circuits.

Frequently Asked Questions

How does the 200 µV maximum offset voltage of INA597IDT affect accuracy in a precision bridge sensor measurement system?

With a maximum input offset voltage of 200 µV, INA597IDT introduces a measurement error equivalent to 200 µV at the input regardless of gain setting. For a 10 mV full-scale bridge output amplified at a gain of 100, this offset represents a 2% error without calibration. The e-trim precision process reduces drift over temperature, allowing designers to use software offset calibration to achieve sub-0.1% accuracy in final systems.

What CMRR does INA597IDT provide, and how does it benefit current sensing on a noisy industrial power rail?

INA597IDT achieves a minimum CMRR of 88 dB (90 dB typical), meaning common-mode noise on an industrial 24 V power rail is attenuated by a factor of over 25,000 relative to the differential signal. For a 1 V peak common-mode noise signal riding on a 24 V bus, the rejected noise at the output would be less than 40 µV, preserving measurement accuracy for current shunt signals as small as 10 mV.

For what bandwidth and gain combination is INA597IDT most suitable in a 4-20 mA industrial loop receiver?

INA597IDT provides a 2 MHz gain-bandwidth product in a voltage-feedback configuration. For a 4-20 mA loop receiver with a shunt resistor producing 0 to 200 mV differential, a gain of 10 V/V yields a 200 kHz signal bandwidth, more than sufficient for standard industrial process signals up to 1 kHz. The low-power 8-SOIC package suits loop-powered transmitter circuits where total current consumption is limited to under 4 mA.
