3 Description
The AMC22C12 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
galvanic isolation of up to 3 kVRMS according to DIN
EN IEC 60747-17 (VDE 0884-17) and UL1577, and
supports a working voltage of up to 560 VRMS.
The comparison window is centered around 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 AMC22C12 is available in a 8-pin SOIC
package and is specified over the extended industrial
temperature range of –40°C to +125°C.
