DUAL AND QUAD DIFFERENTIAL COMPARATORS

Description

Pin Assignments

(Top View)

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.

SO-8/TSSOP-8/MSOP-8

LM2903/ LM2903A

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.
