Product details

What this automotive current-sense amplifier brings to the BOM

It operates from 2.7 V to 36 V, drawing 200 µA supply current, and delivers a gain-bandwidth product of 50 kHz with a 0.2 V/µs slew rate. For a board-level current monitor that needs to survive thermal cycling and vibration, this is the part that fits — the 16-TSSOP body is compact enough for dense ECUs but still reworkable with a hot-air station if a pad lifts.

Bandwidth and slew — where the spec matters

It is not built for high-speed switching waveforms or sub-microsecond fault capture; for that you would step up to the INA254A1IPWAR with 350 kHz bandwidth and 2.4 V/µs slew.

Frequently asked questions

Is INA250A1QPWRQ1 AEC-Q100 automotive qualified?

Yes, the INA250A1QPWRQ1 is AEC-Q100 qualified and carries an Automotive grade rating, making it suitable for automotive applications including under-hood and chassis-domain electronics.

What is the gain bandwidth product of INA250A1QPWRQ1?

The gain-bandwidth product is 50 kHz, with a slew rate of 0.2 V/µs. This suits DC and low-frequency current monitoring applications such as battery monitoring, load detection, and averaged motor current sensing.

What is the replacement or equivalent for INA250A1QPWRQ1?

For a higher-bandwidth alternative in the same footprint and supply range, the INA254A1IPWAR offers 350 kHz bandwidth and 2.4 V/µs slew rate. It is a pin-compatible functional upgrade, not a direct parametric replacement.
