DUAL AND QUAD DIFFERENTIAL COMPARATORS
Description
The LM2901/2903 series comparators consist of four and two
independent precision voltage comparators with very low input offset
voltage specification. They are 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 operating 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, TSSOP-8, MSOP-8 and the
quad devices available in SO-14 and TSSOP-14 with industry
standard pinouts. Both use green mold compound as standard.
