3 Description
The AMC1301-Q1 device is a precision, isolated
amplifier with an output separated from the input
circuitry by an isolation barrier that is highly resistant
to magnetic interference. This barrier is certified to
provide reinforced galvanic isolation of up to 7 kV_PEAK
according to VDE V 0884-10 and UL1577. 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 AMC1301-Q1 device 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 savings and,
especially in motor control applications, lower torque
ripple. The integrated common-mode overvoltage and
missing high-side supply voltage detection features of
the AMC1301-Q1 device simplify system-level design
and diagnostics.
The AMC1301-Q1 device is available in a wide-body
8-pin SOIC (DWV) package.
