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.
