Maxim MAX9643 Current-Sense Amplifiers

Maxim Integrated MAX9643
Current-Sense Amplifiers

Maxim Integrated MAX9643 60V high-speed precision current-sense amplifiers are high-speed unidirectional devices ideal for a wide variety of power-supply control applications. The high signal bandwidth of the MAX9643 allows its use within DC-DC switching converter power-supply control loops with minimal phase delay. These Maxim Integrated current-sense amplifier ICs also feature 50µV (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 makes Maxim Integrated MAX9643 current-sense amplifiers easy to use in a wide variety of environments. These Maxim Integrated devices are ideal for use in industrial and automotive power supplies, GSM base station power supply, and more.
