Packaged in a 4-bump UCSP, the MAX9938 high-side, current-sense amplifier integrates precision resistors. Designed to operate from 1.6 to 28 V, the part is ideal for smart phones, digital cameras, PDAs, MP3 players, notebook computers, and other battery-operated devices.
In addition, the MAX9938 features a ±0.5-mV max input-offset voltage and 0.5% max gain error, for a total error of less than 1% max. The part consumes 1 μA of quiescent current and is offered in three voltage-gain versions of 25, 50, and 100 V/V. (From $0.64 ea/1,000 — available now.)
