Input Basic Isolated Amplifier for Current Sensing, 200uV, 4.25kV, 2.7V to 5.5V, SOIC, 8 Pins - AMC1200BDWV

The AMC1200BDWV is a precision isolation Amplifier with an output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide galvanic isolation of up to 4250VPEAK according to UL1577 and VDE V 0884-10. Used in conjunction with isolated power supplies, this device prevent noise currents on a high common mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry. The input of the amplifier is optimized for direct connection to shunt resistors or other low voltage level signal sources. The excellent performance of the device supports accurate current control resulting in system-level power saving and especially in motor-control applications, lower torque ripple. The common mode voltage of the output signal is automatically adjusted to either the 3V or 5V low-side supply.
