AMC1301-Q1 - Automotive Precision ±250mV-Input 3µs-Delay Reinforced Isolated Amplifier

The AMC1301-Q1 device is a precision, isolated amplifier with anoutput separated from the input circuitry by an isolation barrier that is highly resistant tomagnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to7 kV_PEAK according to VDE V 0884-10 and UL1577. Used in conjunction withisolated power supplies, this device prevents noise currents on a high common-mode voltage linefrom entering the local ground and interfering with or damaging sensitive circuitry.

The input of the AMC1301-Q1 device is optimized for direct connectionto shunt resistors or other low voltage-level signal sources. The excellent performance of thedevice supports accurate current control resulting in system-level power savings and, especially inmotor control applications, lower torque ripple. The integrated common-mode overvoltage and missinghigh-side supply voltage detection features of the AMC1301-Q1 device simplifysystem-level design and diagnostics.

The AMC1301-Q1 device is available in a wide-body8-pin SOIC (DWV) package.
