3 Description

The AMC23C10-Q1 is a precision, isolated

comparator with a short response time. This device

is specifically designed for zero-crossing detection

of high-voltage signals that are galvanically isolated

from low-voltage circuitry. The open-drain and pushpull

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 up to 5kVRMS

according to VDE 0884-17 and UL1577. This barrier

also supports a working voltage 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 highvoltage

side. Thus, 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-Q1 is available in an 8-pin, widebody

SOIC package and is specified over the

extended industrial temperature range of –40°C to

+125°C.
