LMC7221
Tiny CMOS Comparator with Rail-To-Rail Input and Open
Drain Output
General Description
The LM7221 is a micropower CMOS comparator available in
the space saving 5-Pin SOT23 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 sys-
tems.
For a tiny comparator with a push-pull output, please see the
LMC7211 datasheet.
