3 Description

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 5 kVRMS

according to VDE 0884-17 and UL1577, and supports

a working voltage of up to 1 kVPK.

The device offers an open-drain and a push-pull

output with a propagation delay of less than 320 ns.

The integrated low-dropout (LDO) regulator supports

an operating voltage range of 3 V to 27 V on the highvoltage

side, allowing the comparator to be powered

from a wide range of power supplies. The operating

voltage range on the low-side is 2.7 V to 5.5 V.

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.
