The 3 V to 28 V supply span means it runs directly off the rail it is monitoring, whether that is a 3.3 V core bus or a 24 V industrial supply, with no separate bias regulator needed. ## Temperature range and operating environment This is not a commercial-grade part that needs derating at the high end — it holds its specs across the range, which simplifies qualification in engine bay or factory-floor designs where ambient can hit 105°C and internal self-heating pushes the junction higher. ## Package and mounting detail Housed in a 5-lead SC-70-5 (SOT-353) package, the part takes up roughly 2 mm × 2 mm of board area. Surface-mount only, so a pick-and-place step and a reflow profile matching the small-body footprint are assumed. The SC-70-5 is a common package for current-sense amplifiers, making layout straightforward — just a shunt resistor, a decoupling cap, and the sense lines routed as a differential pair to the input pins. ## Lifecycle and compliance For dual-sourcing, look at other Maxim current-sense amps in the same SC-70-5 footprint — the MAX4073 family shares pin compatibility across gain options.","metaTitle":"MAX4073HAXK+T Current Sense Amplifier, 1.6 MHz, SC-70-5","metaDescription":"MAX4073HAXK+T is a 1.6 MHz current sense amplifier in SC-70-5. 3V to 28V supply, -40°C to 125°C range.
