LMC7211
Tiny CMOS Comparator with Rail-to-Rail Input
General 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 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鈥檚 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
