The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification. They have been designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage.
The LM2901/2903 series comparators are designed to directly interface with TTL and CMOS. When operate from both plus and minus power supplies, the LM2901/2903 series comparators will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
The dual devices are available in SO-8 and the quad devices available in SO-14 and TSSOP-14 with industry standard pinouts.
Both use green mold compound as standard.
Wide power supply range:
Single supply: 2V to 36V
Dual supplies: ±1.0V to ±18V
Very low supply current drain– independent of supply voltage
Low input bias current: 25nA
Low input offset current: ±5nA
Typical offset voltage:
Non-A device: 2mV
A device: 1mV
Common-mode input voltage range includes ground
Differential input voltage range equal to the power supply voltage
