Description

The LM139J is one member of the LM139 family.The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Features of the LM139J are:(1)Wide supply voltage range - LM139 series: 2 VDC to 36 VDC or ±1 VDC to ±18 VDC; (2) Very low supply current drain (0.8 mA) - independent of supply voltage; (3) Low input biasing current: 25 nA; (4)Low input offset current: ±5 nA; (5) Offset voltage: ±3 mV; (6) Input common-mode voltage range includes GND; (7) Differential input voltage range equal to the power supply voltage; (8) Low output saturation voltage: 250 mV at 4 mA; (9) Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems.

The absolute maximum ratings of the LM139J can be summarized as:(1)Supply Voltage:36 VDC or ±18 VDC;(2)Differential Input Voltage:36VDC;(3)Input Voltage:-0.3 VDC to +36 VDC;(4)Storage Temperature:-65°C to +150°C;(5)Lead Temperature:260°C;.
