The AMC21C12 is an isolated window comparator with a short response time. The open-drain output is galvanically isolated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. The isolation barrier supports a working voltage up to 200 VRMS or 280 VDC and transient over voltages of up to 570 VRMS or 800 VDC.

The comparison window is centered at 0 V, meaning that the comparator trips if the absolute value of the input voltage exceeds the trip threshold value. The trip threshold is adjustable from 20 mV to 300 mV through a single external resistor and, therefore, the comparison window ranges from ±20 mV to ±300 mV. When the voltage on the REF pin is greater than 550 mV, the negative comparator is disabled and only the positive comparator is functional. The reference voltage in this mode can be as high as 2.7 V. 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.

The AMC21C12 is available in an 8-pin, 0.65-mm pitch VSON package and is specified over the extended industrial temperature range of –40°C to +125°C.
