The AMC1211A-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 basic galvanic isolation ofup to 4.25 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 AMC1211A-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.
