1 / 12 page LMC7221 Tiny CMOS Comparator with Rail-To-Rail Input and Open Drain Output General Description The LM7221 is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes this com- parator ideal for space and weight critical designs. The LMC7221 is also available in the SO-8 package. The LMC7221 is supplied in two offset voltage grades, 5 mV and 15 mV. The open drain output can be pulled up with a resistor to a voltage which can be higher or lower than the supply voltage — this makes the part useful for mixed voltage sys- tems. For a tiny comparator with a push-pull output, please see the LMC7211 datasheet. Features n Tiny SOT 23-5 package saves space n Package is less than 1.43 mm thick n Guaranteed specs at 2.7V, 5V, 15V supplies n Typical supply current 7 µA at 5V n Response time of 4 µs at 5V n LMC7221 — open drain output n Input common-mode range beyond V− and V+ n Low input current Applications n Mixed voltage battery powered products n Notebooks and PDAs n PCMCIA cards n Mobile communications n Alarm and security circuits n Driving low current LEDs n Direct sensor interface Connection Diagrams Ordering Information Package Ordering NSC Drawing Package Transport Media Information Number Marking 8-Pin SO-8 LMC7221AIM M08A LMC7221AIM Rails LMC7221AIMX M08A LMC7221AIM 2.5k Units Tape and Reel LMC7221BIM M08A LMC7221BIM Rails LMC7221BIMX M08A LMC7221BIM 2.5k Units Tape and Reel 5-Pin SOT 23-5 LMC7221AIM5 MA05A C01A 1k Units Tape and Reel LMC7221AIM5X MA05A C01A 3k Units Tape and Reel LMC7221BIM5 MA05A C01B 1k Units Tape and Reel LMC7221BIM5X MA05A C01B 3k Units Tape and Reel 8–Pin SO-8 DS012346-1 Top View 5-Pin SOT23-5 DS012346-2 Top View September 1999 © 1999 National Semiconductor Corporation DS012346 www.national.com |
