LM2903A
LM2903A is DUAL AND QUAD DIFFERENTIAL COMPARATORS manufactured by Diodes Incorporated.
- Part of the LM2901 comparator family.
- Part of the LM2901 comparator family.
Description
The LM2901/2903 series parators consist of four and two independent precision voltage parators 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 parators are designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2901/2903 series parators will directly interface with MOS logic where their low power drain is a distinct advantage over standard parators.
The dual devices are available in SO-8, TSSOP-8, and MSOP-8, and the quad devices available in SO-14 and TSSOP-14 with industry standard pinouts. Both use green mold pound as standard.
