Product details

Automotive-grade shunt measurement

It is a single-channel device with a 400 kHz bandwidth and a 2V/µs slew rate, sized for switching-frequency shunt monitoring in motor-drive and solenoid-control loops without aliasing the PWM edge.

Offset and supply headroom

The 5 µV input offset voltage, characteristic of the zero-drift topology, keeps the measurement error below 0.1 % at a 5 mV full-scale shunt drop across the full temperature range — the decision spec for precision overcurrent and battery-monitoring designs.

Package and sourcing posture

Housed in an 8-TSSOP package (4.40 mm wide), the part is surface-mount and compatible with standard reflow profiles. The supplier device package is 8-TSSOP.

Frequently asked questions

What is the bandwidth and slew rate of INA240A3QPWRQ1?

The -3 dB bandwidth is 400 kHz and the slew rate is 2V/µs, sufficient for monitoring switching frequencies up to several hundred kilohertz in motor-drive and power-converter feedback loops.

What is the difference between INA240A3QPWRQ1 and INA240A1QPWRQ1?

The INA240 family offers multiple gain options that differ in the fixed gain setting. The A3 variant provides a specific gain value; the A1 variant provides a different gain. Both are pin-compatible and share the same package, bandwidth, and automotive qualification. For the exact gain values, refer to the datasheet.
