1FEATURES APPLICATIONS
2• Wide Supply Voltage Range • Limit Comparators
• LM139/139A Series 2 to 36 VDCor ±1 to ±18 VDC • Simple Analog-to-Digital Converters
• LM2901: 2 to 36 VDCor ±1 to ±18 VDC • Pulse, Squarewave and Time Delay Generators
• LM3302: 2 to 28 VDCor ±1 to ±14 VDC • Wide Range VCO; MOS Clock Timers
• Very Low Supply Current Drain (0.8 mA) — • Multivibrators and High Voltage Digital Logic
Independent of Supply Voltage Gates
• Low Input Biasing Current: 25 nA DESCRIPTION
• Low Input Offset Current: ±5 nA The LM139 series consists of four independent
• Offset Voltage: ±3 mV precision voltage comparators with an offset voltage
• Input Common-Mode Voltage Range Includes specification as low as 2 mV max for all four
GND comparators. These were designed specifically to
operate from a single power supply over a wide range
• Differential Input Voltage Range Equal to the of voltages. Operation from split power supplies is
Power Supply Voltage also possible and the low power supply current drain
• Low Output Saturation Voltage: 250 mV at 4 is independent of the magnitude of the power supply
mA voltage. These comparators also have a unique
characteristic in that the input common-mode voltage
• Output Voltage Compatible with TTL, DTL, range includes ground, even though operated from a
ECL, MOS and CMOS Logic Systems single power supply voltage.
ADVANTAGES The LM139 series was designed to directly interface
with TTL and CMOS. When operated from both plus
• High Precision Comparators and minus power supplies, they will directly interface
• Reduced VOS Drift Over Temperature with MOS logic— where the low power drain of the
• Eliminates Need for Dual Supplies LM339 is a distinct advantage over standard
comparators.
• Allows Sensing Near GND
• Compatible with all Forms of Logic
• Power Drain Suitable for Battery Operation
