These comparators were designed specifically to operate from a single power supply • LM3302-N: 2 to 28 VDC or ±1 to ±14 VDC over a wide range of voltages. Operation from split • Very Low Supply Current Drain (0.8 mA) — power supplies is also possible and the low power Independent of Supply Voltage supply current drain is independent of the magnitude • Low Input Biasing Current: 25 nA of the power supply voltage. These comparators also have a unique characteristic in that the input • Low Input Offset Current: ±5 nA common-mode voltage range includes ground, even • Offset Voltage: ±3 mV though they are operated from a single power supply • Input Common-Mode Voltage Range Includes voltage. GND The LMx39-N series was designed to directly • Differential Input Voltage Range Equal to the interface with TTL and CMOS. When operated from Power Supply Voltage both plus and minus power supplies, the devices • Low Output Saturation Voltage: 250 mV at 4 mA directly interface with MOS logic— where the low power drain of the LM339 is a distinct advantage over • Output Voltage Compatible With TTL, DTL, ECL, standard comparators. MOS, and CMOS Logic Systems • Advantages: Device Information(1) – High-Precision Comparators PART NUMBER PACKAGE BODY SIZE (NOM) – Reduced VOS Drift Overtemperature LM139-N CDIP (14) 19.56 mm × 6.67 mm – Eliminates Need for Dual Supplies LM239-N SOIC (14) 8.65 mm × 3.91 mm – Allows Sensing Near GND LM2901-N PDIP (14) 19.177 mm × 6.35 mm – Compatible With All Forms of Logic CDIP (14) 19.56 mm × 6.67 mm – Power Drain Suitable for Battery Operation LM339-N SOIC (14) 8.65 mm × 3.91 mm PDIP (14) 19.177 mm × 6.35 mm 2 Applications (1) For all available packages, see the orderable addendum at • Limit Comparators the end of the datasheet. • Simple Analog-to-Digital Converters (ADCs) • Pulse, Squarewave, and Time Delay Generators One-Shot Multivibrator With Input Lock Out • Wide Range VCO; MOS Clock Timers • Multivibrators and High-Voltage Digital Logic Gates 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
