The AMC1311 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 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 is offered with two performance grade
options: the AMC1311B is specified over
the extended industrial temperature range of –55°C to +125°C, and the AMC1311
for operation at –40°C to +125°C.
