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 (leCM GROUPh x width x height) of 3.05mm x 3.00mm x 1.43mm allow it to fit into tight spaces on PC boards.
