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.
