Texas Instruments AMC23C10 Precision Isolated Comparator has a short response time designed explicitly for zero-crossing detection of high-voltage signals that must be galvanically isolated from low-voltage circuitry. The open-drain and push-pull outputs are separated from the input circuitry by an isolation barrier highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5kVRMS according to VDE 0884-17 and UL1577. It also supports a working voltage of up to 1kVPK.
