Product details

Automotive current-sense amp with zero-drift precision

The INA240A1QPWRQ1 is a single-channel current-sense amplifier from TI's automotive-grade, zero-drift series. It measures current by amplifying the voltage drop across a shunt resistor, and the 5 µV input offset lets it resolve microvolt-level signals without calibration — critical for accurate battery monitoring, solenoid control, and motor-phase current sensing in 12 V and 48 V vehicle systems.

Bandwidth and slew rate for PWM environments

The 1.8 mA supply current keeps the thermal load low in the 8-TSSOP package, which is a common footprint for space-constrained ECU boards.

Surface-mount in an 8-TSSOP package with a 4.40 mm body width — standard for reflow soldering.

Frequently asked questions

Can I use INA240A1QPWRQ1 instead of INA240A2QPWRQ1?

Both are from the same INA240 series and share the same package and supply range, but the gain version differs — the A1 variant has a fixed gain of 20 V/V, while the A2 variant has 50 V/V. Check the gain setting required by your shunt and ADC input range before substituting.

Is INA240A1QPWRQ1 RoHS compliant?
