LMC7221 Tiny CMOS Comparator with Rail-To-Rail Input and Open Drain Output

Check for Samples: LMC7221

FEATURES

DESCRIPTION

The LM7221 is a micropower CMOS comparator

available in the space saving 5-Pin SOT-23 package.

This makes this comparator ideal for space and

weight critical designs. The LMC7221 is also

available in the 8-Pin SOIC package. The LMC7221

is supplied in two offset voltage grades, 5 mV and 15

mV.

•

Tiny 5-Pin SOT-23 package saves space

Package is less than 1.43 mm thick

Ensured specs at 2.7V, 5V, 15V supplies

Typical supply current 7 μA at 5V

Response time of 4 μs at 5V

•

LMC7221—open drain output

Input common-mode range beyond V⁻and V⁺

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 systems.

Low input current

APPLICATIONS

For a tiny comparator with a push-pull output, please

see the LMC7211 datasheet.

•

Mixed voltage battery powered products

Notebooks and PDAs

PCMCIA cards

Mobile communications

Alarm and security circuits

Driving low current LEDs

Direct sensor interface

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.
