The MAX9938 fits in a tiny, 1mm x 1mm UCSP™ package size or a 5-pin SOT23 package, making the part i

MAX9938 Features

* an input common-mode voltage range from 1.6V to 28V. These current-sense amplifiers have a voltage output and are offered in three gain versions: 25V/V (MAX9938T), 50V/V (MAX9938F), and 100V/V (MAX9938H). The three gain selections offer flexibility in the choice of the external current-sense resisto
