MAX9634 Datasheet | Maxim Integrated

Description The MAX9634 high-side current-sense amplifier offers precision accuracy specifications of VOS less than 250μV (max) and gain error less than 0.5% (max). Quiescent supply current is an ultra-low 1μA. The MAX9634 fits in a tiny, 1mm x 1mm UCSP™ package size or a 5-pin SOT23 package, making the part ideal for applications in notebook puters, cell phones, PDAs, and all batteryoperated portable devices where accuracy, low quiescent current, and small size are critical. The MAX9634 features an input mon-mode voltage range from 1.6V to 28V. These current-sense amplifiers have a voltage output and are offered in four gain versions: 25V/V (MAX9634T), 50V/V (MAX9634F), 100V/V (MAX9634H), and 200V/V (MAX9634W). The four gain selections offer flexibility in the choice of the external current-sense resistor. The very low 250μV (max) input offset voltage allows small 25m V to 50m V full-scale VSENSE voltage for very low voltage drop at full-current measurement. The MAX9634 is offered in...
