Product details

Description

The MAX9938 high-side current-sense amplifier offers precision accuracy specifications of V OS less than 500μV (max) and gain error less than 0.5% (max).

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 resistor. The very low 500μV (max) input offset voltage allows small 25mV to 50mV full-scale VSENSE voltage for very low voltage drop at full-current measurement. The MAX9938 is offered in tiny 4-bump, UCSP.
