+ + + + + 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.
