The LMC7211-N is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes the comparator designed for space and weight critical designs. The LMC7211-N is supplied in two offset voltage grades, 5mV and 15mV. 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-N 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 × 3.00mm × 1.43mm allow the device to fit into tight spaces on PC boards. See the LMC7221 for a comparator with an open-drain output.
