What this part is and where it fits
The MAX9610HELT+T is a single-channel current sense amplifier from Analog Devices, built for low-side current monitoring in battery-powered or power-sensitive designs. It draws 750 nA supply current, which keeps the quiescent load off the rail in always-on systems like portable instruments or IoT edge nodes. The 60 kHz bandwidth handles DC rail monitoring and low-frequency load transients, not high-speed switching loops. Input offset voltage is 100 µV, setting the floor for the minimum detectable drop across the sense resistor. Supply span runs from 1.6 V to 5.5 V. The 6-µDFN package (2x2 mm) fits tight layouts. Operating temperature is -40°C to 85°C.
Key ratings and what they mean for your BOM
The 750 nA supply current is the headline feature. A standard op-amp might draw more supply current. The 60 kHz bandwidth sets the upper frequency for accurate current measurement. If you need to capture switching ripple above 60 kHz or fast fault transients, this part is not the right fit. For DC load monitoring, battery charge/discharge tracking, or overcurrent detection with a response time in the tens of microseconds, it works well. Input offset voltage of 100 µV sets the floor for the minimum detectable drop across the sense resistor.
