DESCRIPTION

The LM7221 is a micropower CMOS comparator

available in the space saving 5-Pin SOT-23 package.

This makes this comparator ideal for space and

weight critical designs. The LMC7221 is also

available in the 8-Pin SOIC package. The LMC7221

is supplied in two offset voltage grades, 5 mV and 15 mV.

The open drain output can be pulled up with a

resistor to a voltage which can be higher or lower

than the supply voltage—this makes the part useful

for mixed voltage systems.

For a tiny comparator with a push-pull output, please

see the LMC7211 datasheet.
