That quiescent floor matters when the amp sits across a shunt on a battery rail that stays on 24/7 — the 1.1 µA load is below the self-discharge rate of most lithium cells, so it doesn't eat into the standby budget. Input offset voltage is trimmed to 100 µV typical, which translates to a few milliamps of readout error on a typical 10 mΩ sense resistor — tight enough for fuel-gauging and overcurrent detection in portable gear. ## Active production — no end-of-life watch needed Design-in for new builds is straightforward — no last-time-buy planning required. ## SOT-23-5 footprint — tape & reel for volume assembly Housed in a SC-74A / SOT-23-5 package (supplier device package SOT-23-5), the MAX9634HEUK+T is supplied on tape & reel (7-inch reel, 3000-piece quantity typical). The 5-pin footprint is a standard surface-mount layout shared across many current-sense amps, so PCB layout reuse is common. Single-circuit per package — for multi-rail monitoring (e.g., separate battery, 3.3 V, 1.8 V rails), each rail gets its own device. The low 1.1 µA per channel keeps the aggregate overhead manageable.","metaTitle":"MAX9634HEUK+T nanoPower Current Sense Amp, 1.1µA, SOT-23-5","metaDescription":"Analog Devices MAX9634HEUK+T nanoPower current sense amplifier: 1.1 µA supply, 125 kHz GBW, 100 µV offset, SOT-23-5.
