The dual-channel configuration lets you monitor two independent rails — for example, a 12 V power bus and a 5 V peripheral rail — without adding a second amplifier IC. The supply range spans 3 V to 28 V, which covers 3.3 V logic rails up through 24 V industrial buses. The 2 MHz bandwidth sets the upper frequency of current ripple the amplifier can track. If you are sensing current in a switching power supply running at 500 kHz, the amplifier will pass the fundamental and a couple of harmonics, giving you a usable waveform for overcurrent detection or average-current feedback. The 10V/µs slew rate means the output can swing from near ground to 2 V in about 200 ns, which is fast enough to catch a short-circuit transient on a 24 V bus before the downstream regulator folds back. For slower loads — a battery charger, a DC fan — the bandwidth is more than adequate, and the slew rate gives you clean edge response without ringing. The 3 V minimum supply lets this part run directly from a 3.3 V rail, which is common in modern MCU-based designs. The 28 V maximum gives headroom on a nominal 24 V supply — you can tolerate a 4 V overvoltage transient without exceeding the absolute maximum. Each channel draws 1 mA typical, so the total supply current is 2 mA — negligible in a system that already burns 50 mA for the microcontroller. ## Lifecycle status and sourcing posture There is no LTB window to track, and no forced migration to a successor package.","metaTitle":"MAX4377TEUA Current Sense Amplifier, Dual, 2 MHz, 10V/µs","metaDescription":"MAX4377TEUA dual current sense amplifier from Analog Devices. 2 MHz bandwidth, 10V/µs slew rate, 3 V to 28 V supply, -40°C to 125°C.

The MAX4377TEUA is a current sense amplifier designed to measure the voltage across a shunt resistor. It can be configured for high-side sensing (shunt between the supply and the load) as long as the common-mode voltage stays within the supply range.
