LMC7211 Tiny CMOS Comparator with Rail-to-Rail Input and Push-Pull Output Check for Samples: LMC7211-N FEATURES APPLICATIONS 1 • Tiny SOT 23-5 package saves space • Battery Powered Products 2 • Package is less than 1.43 mm thick • Notebooks and PDAs • Guaranteed specs at 2.7V, 5V, 15V supplies • PCMCIA cards • Typical supply current 7 μA at 5V • Mobile Communications • Response time of 4 μs at 5V • Alarm and Security circuits • Push-pull output • Direct Sensor Interface • Input common-mode range beyond V− and V+ • Replaces amplifiers used as comparators with better performance and lower current • Low input current 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
