Its 100 kHz -3 dB bandwidth supports dc current monitoring plus ripple or transient capture up to that frequency — fast enough for most motor-drive, solenoid, and power-supply output rails, but not for switching-node edge detection. The input offset voltage is trimmed to 80 µV, which sets the floor for measurement error at low shunt drops. With a 10 mΩ shunt, 80 µV offset corresponds to 8 mA of apparent current — acceptable for a 10 A rail but too coarse for sub-100 mA idle-current tracking. The 2.4 µA input bias current flows through the shunt and adds a small voltage drop that is common-mode, not differential, so it cancels in the amplifier's gain stage. ## Supply span and quiescent current for always-on rails The 100 µA supply current is low enough to leave the amplifier powered continuously on a battery-backed rail — the quiescent draw is 2.4 mW at 24 V, negligible in a system that already dissipates watts in the load. The 8-uMAX/uSOP package is a 3 mm × 3 mm footprint with 0.65 mm pin pitch — the same as the 8-MSOP land pattern, so the PCB layout is shared with other uMAX-packaged parts in the same BOM position. ## Active production and compliance posture The Tape & Reel (TR) packaging option is suited for automated pick-and-place assembly. The Cut Tape (CT) variant is also listed for prototype or low-volume builds.","metaTitle":"MAX4070AUA+T Current Sense Amplifier, 100 kHz, 8-uMAX","metaDescription":"Analog Devices MAX4070AUA+T current sense amplifier, 100 kHz bandwidth, 80 µV offset, 100 µA supply.

This means the amplifier accurately reproduces dc current levels and ac ripple or transients up to 100 kHz. Above that frequency the gain rolls off — switching edges above 100 kHz will be attenuated, so the part is not intended for high-frequency switching-node current sensing."},{"question":"What package does the MAX4070AUA+T come in?","answer":"It is supplied in an 8-uMAX/uSOP surface-mount package, which is the same 3 mm × 3 mm footprint as the 8-MSOP.
