Description

General part information

AMC23C12 Series

The AMC23C12 is an isolated window comparator with a short response time. The open-drain output is 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 comparison window is centered around 0V, meaning that the comparator trips if the absolute value of the input voltage exceeds the trip threshold value. The trip threshold is adjustable from 20mV to 300mV through a single external resistor and, therefore, the comparison window ranges from ±20mV to ±300mV. When the voltage on the REF pin is greater than 550mV, the negative comparator is disabled and only the positive comparator is functional. The reference voltage in this mode ranges as high as 2.7V. This mode is particularly useful for monitoring voltage supplies.

The open-drain output on the device supports transparent mode (LATCH input tied to GND2) where the output follows the input state, or latch mode, where the output is cleared on the falling edge of the latch input signal.
