LMC7211 - National Semiconductor

LMC7211 Tiny CMOS Comparator

The LMC7211 is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes the comparator ideal for space and weight critical designs. The LMC7211 is supplied in two offset voltage grades, 5 mV and 15 mV. The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, not.
