Below that, the amplifier tracks the shunt voltage with minimal gain error. The 2 V/µs slew rate means the output can swing quickly enough for PWM ripple monitoring in a switching supply, but not for fast transient capture above a few hundred kilohertz. If your load step is faster than that, you need a wider-bandwidth part. ## Package and mounting — field-swappable size SOT-23-6 is a small, surface-mount package. It fits on tight PCB layouts and can be hand-soldered or reflowed. The 6-pin footprint is standard; orientation is clear from the pin-1 marker. No special handling beyond normal ESD precautions.","metaTitle":"TI INA181A2IDBVT Current Sense Amplifier, SOT-23-6, 350 kHz","metaDescription":"Texas Instruments INA181A2IDBVT current sense amplifier in SOT-23-6, 350 kHz bandwidth, 2.7 V to 5.5 V supply.
