ADM4073 is a low-cost, voltage output, high-side current sense amplifier. Its features include selectable gain versions, ±1.0% full-scale accuracy, 500µA supply current, etc.
The ADM4073 is a high‑side current‑sense amplifier designed for portable applications such as cell phones, notebooks, and battery‑powered systems. It operates from 3 V to 28 V, draws a typical supply current of 500 µA, and offers a wide common‑mode range of 2 V to 28 V.
Three gain options (20 V/V, 50 V/V, 100 V/V) eliminate the need for external gain‑setting resistors. The device is supplied in a 6‑lead SOT‑23 package and is qualified for automotive temperature ranges (‑40 °C to +125 °C).
