DESCRIPTION

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, notebook computers, personal digital assistants, and PCMCIA cards. The rail-to-rail input

voltage makes the LMC7211 a good choice for sensor interfacing, such as light detector circuits, optical and

magnetic sensors, and alarm and status circuits.

The Tiny Comparator's outside dimensions (length x width x height) of 3.05mm x 3.00mm x 1.43mm allow it to fit

into tight spaces on PC boards.

See the LMC7221 for a comparator with an open-drain output.
