Product details

With a gain-bandwidth product of 105 kHz and a slew rate of 2 V/µs, this part handles DC-to-mid-frequency current sensing. It is sized for monitoring solenoid currents, motor-phase currents at PWM frequencies below 20 kHz, and battery-charge/discharge rates where the signal content is well below 100 kHz.

Supply current and input offset — the BOM-fit details

Quiescent supply current is 197 µA typical, low enough for always-on sensing in modules that stay powered during ignition-off periods.

Supplied in a SOT-23-5 package (SC-74A, SOT-753 equivalent), this is a surface-mount part with 0.95 mm pitch — standard for automated assembly.

Frequently asked questions

Is INA180A4QDBVRQ1 the same as INA180A4QDBVR?

The INA180A4QDBVRQ1 and INA180A4QDBVR share the same base product number INA180 and the same SOT-23-5 package. The Q1 suffix indicates AEC-Q100 automotive qualification. The non-Q1 variant is the commercial-grade version; the Q1 is the one to specify for automotive BOMs.
