LMC7211
Tiny CMOS Comparator with Rail-to-Rail Input
General Description
Features
Y
Tiny SOT 23-5 package saves space
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 available in SO-8 surface mount packages and
in conventional 8-pin DIP packages. The LMC7211 is sup-
plied 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.
