Description
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.
