Description:
The Microchip Technology, Inc. MCP6566/6R/6U/7/9
families of open-drain output comparators are offered
in single, dual and quad configurations.
These comparators are optimized for low-power 1.8V,
single-supply applications with greater than rail-to-rail
input operation. The internal input hysteresis eliminates
output switching due to internal input noise voltage,
reducing current draw. The open-drain output of the
MCP6566/6R/6U/7/9 family requires a pull-up resistor
and it supports pull-up voltages above and below VDD,
which can be used to level shift. The output toggle
frequency can reach a typical of 4 MHz (typical) while
limiting supply current surges and dynamic power
consumption during switching.
This family operates with single supply voltage of 1.8V
to 5.5V while drawing less than 100 µA/comparator of
quiescent current (typical).
