The AMC1311 is a precision,
isolated amplifier with an output separated from the input circuitry by a capacitive
isolation barrier that is highly resistant to magnetic interference. This barrier is
certified to provide reinforced galvanic isolation of up to 5 kVRMS
according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 and supports a working
voltage of up to 1500 VRMS.The isolation barrier separates parts
of the system that operate on different common-mode voltage levels and protects the
low-voltage side from voltages that can cause electrical damage or be harmful to an
operator.The high-impedance input of the AMC1311 is optimized for connection to high-impedance resistive
dividers or any other high-impedance voltage signal source. The excellent DC
accuracy and low temperature drift support accurate, isolated voltage 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 is specified for operation at –40°C to +125°C.
