3 Description
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.
