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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
