The 150 kHz bandwidth sets the usable signal frequency for current monitoring — fast enough to capture PWM ripple in a motor drive or load-step response in a power supply, but not intended for RF or high-speed data links. ## Package, footprint, and shelf life Store the reels dry — the MSL level is not stated in this record, but standard SOIC-8 is typically MSL 1 or 2; if unsure, bake per J-STD-033 before reflow. ## Temperature grade and operating envelope The 125°C upper limit covers under-hood or engine-bay deployment where the local ambient can reach 105°C with self-heating margin. The 103 µA supply current keeps the quiescent draw low enough for always-on monitoring in battery-powered systems — the amplifier itself does not dominate the sleep budget. ## DC accuracy and input characteristics For a typical 10 mΩ shunt carrying 10 A, the sense voltage is 100 mV; the 100 µV offset contributes 0.1% error before any gain-stage drift. The 5 µA bias flows through the shunt and adds a small voltage drop — negligible for shunts below 1 Ω but worth checking for high-value sense resistors.","metaTitle":"MAX4081TASA+T Current Sense Amplifier, 8-SOIC, 150 kHz","metaDescription":"MAX4081TASA+T high-side current sense amplifier from Analog Devices. 4.5-76V supply, 150 kHz bandwidth, 8-SOIC.
