AMC1301QDWVQ1

The AMC1301-Q1 device is an isolated precision amplifier. The output and input circuits of this amplifier are separated by an isolation layer with extremely strong anti-electromagnetic interference performance. According to the VDE V 0884-10 and UL1577 standards, this isolation barrier is certified to provide enhanced current isolation up to 7 kVPEAK. When used with an isolated power supply, this device can prevent noise currents on common-mode high-voltage lines from flowing into the local ground and interfering with or damaging sensitive circuits. The input of the AMC1301-Q1 device is optimized for direct connection to shunt resistors or other low-voltage signal sources. This device features excellent performance and supports precise current control, thereby reducing system-level power consumption (especially in motor control applications) and minimizing torque ripple. The integrated common-mode overvoltage and high-side power supply voltage loss detection features of this device (AMC1301-Q1) can simplify system-level design and diagnosis. The AMC1301-Q1 device is available in a wide-body 8-pin SOIC (DWV) package.
