MAXIM INTEGRATED PRODUCTS MAX9643UATA+T 电流检测放大器, 高速精准, 1个放大器, 35 µA, TDFN, 8 引脚, -40 °C, 125 °C
The is a high speed 60V precision current sense amplifier in 8 pin TDFN package. This unidirectional current sense amplifier is ideal for a wide variety of power supply control applications. Its high signal bandwidth allows this device to use within DC to DC switching converter power supply control loops with minimal phase delay. The IC also has 130µV maximum 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 wide variety of aggressive environments. The MAX9643U is used in GSM base station power supply and high brightness LED control applications.
