Description for the AMC1311-Q1

The AMC1311-Q1 is a precision, isolated amplifier with an outputseparated from the input circuitry by an isolation barrier that is highly resistant to magneticinterference. This barrier is certified to provide reinforced galvanic isolation ofup to 7 kVPEAK according to VDE V 0884-11and UL1577. Used in conjunction with isolated power supplies, this isolated amplifier separatesparts of the system that operate on different common-mode voltage levels and protects lower-voltageparts from damage.

The high-impedance input of the AMC1311-Q1 is optimized for connectionto high-voltage resistive dividers or other voltage signal sources with high output resistance. Theexcellent performance of the device supports accurate, low temperature drift voltage or temperaturesensing and control in closed-loop systems. The integrated missing high-side supply voltagedetection feature simplifies system-level design and diagnostics.

The AMC1311-Q1 is offered with two performance gradeoptions: AMC1311-Q1 and AMC1311B-Q1.
