AMC1302에 대한 설명
The AMC1302 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 5 kVRMS according to VDE V 0884-11 and UL1577, and supports a working voltage of up to 1.5 kVRMS.
The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from hazardous voltages and damage.
The input of the AMC1302 is optimized for direct connection to a low-impedance shunt resistor or other low-impedance voltage source with low signal levels. The excellent DC accuracy and low temperature drift supports accurate current control in PFC stages, DC/DC converters, AC-motor and servo drives over the extended industrial temperature range from –40°C to +125°C.
The integrated missing-shunt and missing high-side supply detection features simplify system-level design and diagnostics.
