Description for the AMC1211-Q1
The AMC1211-Q1 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 basic galvanic isolation of up to 3 kVRMS according to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, and supports a working voltage of up to 1000 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 AMC1211-Q1 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 AMC1211-Q1 is offered in a wide-body 8-pin SOIC package and is AEC-Q100 qualified for automotive applications and supports the temperature range from –40°C to +125°C.
