ILEAKAGE Output Leakage Current V+ = 2.7V VIN(+) = 0.5V 0.1 500 500 nA VIN(−) = 0V VOUT = 15V (1) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (2) All limits are specified by testing or statistical analysis.

Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (2) All limits are specified by testing or statistical analysis. (3) Do not short circuit the output to V+ when V+ is greater than 12V or reliability will be adversely affected. (4) Input offset voltage average drift is calculated by dividing the accelerated operating life VOS drift by the equivalent operational time. This represents worst case input conditions and includes the first 30 days of drift. 4 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LMC7221 Document Outline FEATURES Applications DESCRIPTION Connection Diagram Absolute Maximum Ratings Operating Ratings 2.7V Electrical Characteristics 5.0V and 15.0V Electrical Characteristics Leakage Characteristics AC Electrical Characteristics Typical Performance Characteristics Application Information BENEFITS OF THE LMC7221 TINY COMPARATOR Size Height Simplified Board Layout Low Supply Current Wide Voltage Range Digital Outputs Representing Signal Level Open Drain Output Driving LEDs (Light Emitting Diodes) Input range to Beyond Rail to Rail Zero Crossing Detector Low Input Currents and High Input Impedance Direct Sensor Interfacing LOW VOLTAGE OPERATION OPEN DRAIN OUTPUT Output Stage OUTPUT SHORT CIRCUIT CURRENT INPUT PROTECTION LAYOUT CONSIDERATIONS PUSH-PULL OUTPUTS, DUAL VERSIONS ADDITIONAL 5-Pin SOT-23 TINY DEVICES SPICE MACROMODEL Revision History
