Input offset voltage is trimmed to 100 µV, and input bias current is 5 µA — both numbers that feed into the total measurement error budget when you stack gain and drift terms. ## Supply range and bandwidth — what they mean for the BOM 150 kHz bandwidth is enough to resolve switching ripple at typical SMPS frequencies but not full switching edges. ## Error budget stacking for a current-sense design The 100 µV input offset voltage sets the floor on measurable current. The 5 µA input bias current adds a second error term. ## Package and mounting Housed in an 8-uMAX/uSOP (3.00 mm width, 0.118\" body), surface-mount only. Tape & Reel or Cut Tape options are available. ## Lifecycle and sourcing reality No last-time-buy risk for new designs. ROHS3 compliant. For BOM freeze or dual-source planning, verify the exact suffix (FAUA+T) for your design.","metaTitle":"MAX4081FAUA+T Current Sense Amplifier, 150 kHz, 76 V","metaDescription":"MAX4081FAUA+T current sense amplifier from Analog Devices. 4.5 V to 76 V supply, 150 kHz bandwidth, 103 µA supply current.
