EVALUATION KIT AVAILABLE MAX9938 nanoPower, 4-Bump UCSP/SOT23, Precision Current-Sense Amplifier General Description Features The MAX9938 high-side current-sense amplifier offers Ultra-Low Supply Current of 1A (max) precision accuracy specifications of V less than 500V OS Low 500V (max) Input Offset Voltage (max) and gain error less than 0.5% (max). Quiescent Low < 0.5% (max) Gain Error supply current is an ultra-low 1A. The MAX9938 fits in a tiny, 1mm x 1mm UCSP package size or a 5-pin Input Common Mode: +1.6V to +28V SOT23 package, making the part ideal for applications in Voltage Output notebook computers, cell phones, PDAs, and all battery- Four Gain Versions Available operated portable devices where accuracy, low quiescent +25V/V (MAX9938T) current, and small size are critical. 50V/V (MAX9938F) The MAX9938 features an input common-mode voltage 100V/V (MAX9938H) range from 1.6V to 28V. These current-sense ampli- 200V/V (MAX9938W) fiers have a voltage output and are offered in four gain Tiny 1mm x 1mm x 0.6mm, 4-Bump UCSP, 5-Pin versions: 25V/V (MAX9938T), 50V/V (MAX9938F), SOT23, or 2mm x 2mm x 0.8mm, 6-Pin DFN 100V/V (MAX9938H), and 200V/V (MAX9938W).
