LMC7211 Tiny CMOS Comparator with Rail-to-Rail Input and Push-Pull Output
September 1999
LMC7211
Tiny CMOS Comparator with Rail-to-Rail Input and
Push-Pull Output
General Description
The LMC7211 is a micropower CMOS comparator available
in the space saving SOT23-5 package. This makes the com-
parator 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.
