The 1.8 MHz -3dB bandwidth means it resolves fast load transients — useful for monitoring the current draw of a switching regulator output or a motor phase that changes load in microseconds. ## Signal-chain fit and power budget Quiescent supply current is 500 µA — low enough that the amplifier's own draw does not eat into the load budget on a battery-powered board, but not a nano-power part for always-on sensing. The 40 µA input bias current is the current that flows into the sense inputs; it adds a voltage drop across the external gain-setting resistors that must be accounted for in the measurement error budget. Input offset voltage is 1 mV. At the output, this offset appears multiplied by the gain of the external sense resistor and the amplifier's internal gain. For a 10 mΩ sense resistor carrying 1 A, the sense voltage is 10 mV — a 1 mV offset is a 10 % error at the low end of the range, so the resistor value and gain should be chosen to keep the sense voltage well above the offset floor. ## Package and reflow reality Housed in a 5-lead SC-70-5 (SOT-353), the MAX4073TAXK+T has a 0.65 mm lead pitch and a body that sits about 1.0 mm tall. The small footprint saves board space but the fine pitch means the solder paste stencil aperture needs to be sized correctly — a 0.4 mm square aperture per lead with a 0.125 mm stencil thickness is typical. No exposed pad, so the thermal path is through the leads only; the 500 µA supply current keeps self-heating negligible. MSL level is not explicitly stated in the record, but for a standard SC-70-5 package from Analog Devices, MSL-1 is typical — no bake required before reflow unless the bag has been opened for longer than the floor life. The tape-and-reel format feeds directly into a pick-and-place feeder; the SC-70-5 body is small enough that nozzle selection matters — a 0.7 mm or 0.8 mm ID nozzle with a flat tip holds it without tipping. It lives in an engine bay ECU, a solar inverter enclosure, or a factory-floor sensor node without derating at the hot end.","metaTitle":"MAX4073TAXK+T Current Sense Amplifier, 1.8 MHz, SC-70-5","metaDescription":"Analog Devices MAX4073TAXK+T current sense amplifier, 1.8 MHz bandwidth, 500 µA supply, SC-70-5.
