MAX9643 60V High-Speed Precision Current-Sense Amplifier
■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 band-width allows its use within DC-DC switching converter power-supply control loops with minimal phase delay.
■The IC also features 130μV (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.
■High DC CMRR and AC CMRR make it easy to use in a wide variety of aggressive environments. The device is available in fixed gains of 2.5V/V and 10V/V. It is also available in a small, 8-pin TDFN (2mm x 3mm) package and is rated over the -40°C to +125°C temperature range.
●Benefits and Features:
