General Description
The MAX9643 is a high-speed 60V precision unidirectional current-sense amplifier ideal for a wide variety of power-supply control applications. Its high signal bandwidth allows its use within DC-DC switching converter power-supply control loops with minimal phase delay.
The IC also features 50FV (max) precision input offset voltage, allowing small sense resistors to be used in applications where efficiency is important and when wide dynamic-range current measurement is needed.
