The AMC23C10 is a precision, isolated comparator with a short response time that is specifically designed 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 that is 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, and supports a working voltage of up to 1kVRMS.
The device offers an open-drain and a push-pull output with a propagation delay of less than 320ns. The integrated low-dropout (LDO) regulator supports an operating voltage range of 3V to 27V on the high-voltage side, allowing the comparator to be powered from a wide range of power supplies. The operating voltage range on the low-side is 2.7V to 5.5V.
The AMC23C10 is available in an 8-pin, wide-body SOIC package and is specified over the extended industrial temperature range of –40°C to +125°C.
