The AMC1311-Q1 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 kVPEAK according to VDE V 0884-11 and UL1577. Used in conjunction with isolated power supplies, this isolated amplifier separates parts of the system that operate on different common-mode voltage levels and protects lower-voltage parts from damage.
The high-impedance input of the AMC1311-Q1 is optimized for connection to high-voltage resistive dividers or other voltage signal sources with high output resistance. The excellent performance of the device supports accurate, low temperature drift voltage or temperature sensing and control in closed-loop systems. The integrated missing high-side supply voltage detection feature simplifies system-level design and diagnostics.
The AMC1311-Q1 is offered with two performance grade options: AMC1311-Q1 and AMC1311B-Q1.
