Its 125 kHz bandwidth limits it to DC and low-frequency current monitoring — think battery charge/discharge profiles, power-supply output tracking, or motor phase currents at fundamental frequency, not high-speed switching edges. Drawing just 1.1 µA from the supply, this part is sized for always-on monitoring in battery-powered gear — a sensor node logging current every few seconds sees the amplifier's own draw as a negligible fraction of the system sleep current. ## Supply range and temperature grade — where it fits Input offset voltage is 100 µV typical, which sets the floor on measurement accuracy at low shunt voltages — a 10 mΩ shunt carrying 100 mA drops only 1 mV, so the offset contributes a 10% error at that point; a larger shunt or higher sense voltage improves the ratio.","metaTitle":"MAX9938TEUK+T Current Sense Amplifier, 1.1µA, SOT-23-5","metaDescription":"Analog Devices MAX9938TEUK+T current sense amplifier in SOT-23-5. 125 kHz bandwidth, 1.1µA supply, 1.6V to 28V range.
