The AMC1200-Q1 is a precision isolation amplifier with the output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier is certified to provide galvanic isolation of up to 4250 VPEAK according to UL1577 and VDE V 0884-10. Used in conjunction with isolated power supplies, this device prevents 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 AMC1200-Q1 is optimized for direct connection to shunt resistors or other low-voltage level signal sources. The performance of the device supports accurate current control, resulting in systemlevel 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 3-V or 5-V low-side supply.
●The AMC1200-Q1 is available in a wide-body, 8-pin SOIC package (DWV) and a gullwing, 8-pin SOP package (DUB).
