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.
