The LMx39x and the LM2901x devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. .
•1 Wide Supply Ranges
– Single Supply: 2 V to 36 V (Tested to 30 V for Non-V Devices and 32 V for V-Suffix Devices)
– Dual Supplies: ±1 V to ±18 V (Tested to ±15 V for Non-V Devices and ±16 V for V-Suffix Devices)
• Low Supply-Current Drain Independent of Supply Voltage: 0.8 mA (Typical)
• Low Input Bias Current: 25 nA (Typical)
• Low Input Offset Current: 3 nA (Typical) (LM139)
• Low Input Offset Voltage: 2 mV (Typical)
• Common-Mode Input Voltage Range
Includes Ground
• Differential Input Voltage Range Equal to
Maximum-Rated Supply Voltage: ±36 V
• Low Output Saturation Voltage
