Its 1.4 MHz -3dB bandwidth means it can track current transients in switching power supplies or motor-drive phases without significant phase lag — useful when the control loop needs to see the inductor current ramp, not just the DC average. Supply current is 420 µA, low enough that the sense circuit won't dominate the standby budget in a battery-powered system. The input offset voltage is 300 µV, which translates to a few milliamps of readout error on a typical 10 mΩ shunt — fine for overcurrent detection, but worth derating if you need precision below 1 A. ## Supply span: 3 V to 28 V — fits 24 V industrial rails The supply range runs from 3 V minimum to 28 V maximum, so it can sit directly on a 24 V industrial bus with 4 V of headroom for transients. No external pre-regulator needed for that rail. The input bias current is 100 µA — high enough that you need to account for the voltage drop across the shunt's PCB trace resistance, especially with long sense lines. ## Package and mounting — SOT-23-6, surface mount The device comes in a SOT-23-6 package with surface-mount termination.","metaTitle":"MAX4173TEUT Current Sense Amplifier, 1.4 MHz, SOT-23-6","metaDescription":"MAX4173TEUT current sense amplifier in SOT-23-6, 1.4 MHz bandwidth, 420 µA supply, 3 V to 28 V span, -40°C to 85°C.
