Product details

What the INA240A1EDRQ1 does on the board

It measures current across a shunt resistor and outputs a voltage proportional to the shunt drop, with a 400 kHz bandwidth and a 2V/µs slew rate that keep up with fast load transients in motor-drive and solenoid circuits. The 5 µV input offset voltage and zero-drift architecture mean the output error stays small over temperature and time — important when the sense voltage across the shunt is only a few millivolts at light load.

8-SOIC package with 0.154-inch body width — the same footprint as a standard SOIC-8 op-amp. The 1.8 mA quiescent supply current is low enough that the amplifier does not dominate the thermal budget in a sealed ECU enclosure.

Frequently asked questions

What is the exact gain of the INA240A1EDRQ1?

The INA240A1EDRQ1 is a fixed-gain variant; the gain setting is determined by the suffix in the INA240 family. For the A1 version, the gain is 20 V/V. This is a zero-drift architecture, so the gain error drifts very little over temperature.

Is the INA240A1EDRQ1 AEC-Q100 qualified?

Yes, the INA240A1EDRQ1 is part of the Automotive, AEC-Q100 series. It is qualified for automotive-grade stress tests and is suitable for under-hood and chassis-domain applications.
