Wide supply voltage range
LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC
LM2901: 2 to 36 VDC or ±1 to ±18 VDC
LM3302: 2 to 28 VDC or ±1 to ±14 VDC
Very low supply current drain (0.8 mA) — independent
of supply voltage
Low input biasing current: 25 nA
Low input offset current: ±5 nA
Offset voltage: ±3 mV
Input common-mode voltage range includes GND
Differential input voltage range equal to the power
supply voltage
Low output saturation voltage: 250 mV at 4 mA
Output voltage compatible with TTL, DTL, ECL, MOS
and CMOS logic systems
The Advantages of LM393
