+ + + + + LM2901Q/ LM2901AQ/ LM2903Q/ LM2903AQ AUTOMOTIVE COMPLIANT DUAL AND QUAD DIFFERENTIAL COMPARATORS Description Pin Assignments The LM2901Q/2903Q series comparators consist of four and two independent precision voltage comparators with very low input offset LM2903Q/ LM2903AQ voltage specification. They are designed to operate from a single power supply over a wide range of voltages however operation from (Top View) split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage. 1OUT 1 8 VCC The LM2901Q/2903Q series comparators are designed to directly 2 7 1IN- - 2OUT 1 interface with TTL and CMOS. - 3 6 1IN+ 2IN- 2 The LM2903Q dual devices are available in SO-8, MSOP-8 and + 4 2IN+ GND 5 TSSOP-8 and the LM2901Q quad devices are available in SO-14 and TSSOP-14 - all are in industry-standard pinouts. SO-8/TSSOP-8/MSOP-8 All use green mold compound and are qualified to AEC-Q100 Grade 1 and are Automotive Compliant supporting PPAPs.
