V 25°C 1 2 V CC = 5 V to 30 V, VO = 1.4 V IO Input offset voltage mV VIC = VICR(min) Full range 4 25°C 5 50 IIO Input offset current VO = 1.4 V nA Full range 150 25°C –25 –250 IIB Input bias current VO = 1.4 V nA Full range –400 0 to 25°C VCC – 1.5 VICR Common-mode input-voltage range(2) V 0 to Full range VCC – 2 Large-signal differential-voltage V A CC = 15 V, VO = 1.4 V to 11.4 V, VD 25°C 50 200 V/mV amplification RL ≥ 15 kΩ to VCC VOH = 5 V, VID = 1 V 25°C 0.1 50 nA IOH High-level output current VOH = 30 V, VID = 1 V Full range 1 µA 25°C 110 400 VOL Low-level output voltage IOL = 4 mA, VID = –1 V mV Full range 700 IOL Low-level output current VOL = 1.5 V, VID = –1 V, 25°C 6 mA VCC = 5 V 25°C 0.60 1 ICC Supply current RL = ∞ mA VCC = 30 V Full range 0.72 2.5 (1) Full range (minimum or maximum) for LM293A is –25°C to 85°C, and for LM393A is 0°C to 70°C. All characteristics are measured with zero common-mode input voltage, unless otherwise specified. (2) The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state. Either or both inputs can go to maximum VCC level without damage. 8 Submit Documentation Feedback Copyright © 1979–2017, Texas Instruments Incorporated Product Folder Links: LM193 LM293 LM293A LM393 LM393A LM2903 LM2903V Document Outline 1 Features 2 Applications 3 Description Table of Contents 4 Revision History 5 Pin Configuration and Functions 6 Specifications 6.1 Absolute Maximum Ratings 6.2 ESD Ratings 6.3 Recommended Operating Conditions 6.4 Thermal Information LM293, LM393, LM2903 (all suffixes) 6.5 Thermal Information LM193 6.6 Electrical Characteristics for LM193, LM293, and LM393 (without A suffix) 6.7 Electrical Characteristics for LM293A and LM393A 6.8 Electrical Characteristics for LM2903, LM2903V, and LM2903AV 6.9 Switching Characteristics (all devices) 6.10 Typical Characteristics 7 Detailed Description 7.1 Overview 7.2 Functional Block Diagram 7.3 Feature Description 7.4 Device Functional Modes 7.4.1 Voltage Comparison 8 Application and Implementation 8.1 Application Information 8.2 Typical Application 8.2.1 Design Requirements 8.2.2 Detailed Design Procedure 8.2.2.1 Input Voltage Range 8.2.2.2 Minimum Overdrive Voltage 8.2.2.3 Output and Drive Current 8.2.2.4 Response Time 8.2.3 Application Curves 9 Power Supply Recommendations 10 Layout 10.1 Layout Guidelines 10.2 Layout Example 11 Device and Documentation Support 11.1 Related Links 11.2 Receiving Notification of Documentation Updates 11.3 Community Resources 11.4 Trademarks 11.5 Electrostatic Discharge Caution 11.6 Glossary 12 Mechanical, Packaging, and Orderable Information
