AUTOMOTIVE COMPLIANT DUAL AND QUAD DIFFERENTIAL COMPARATORS
Description
The LM2901Q/2903Q 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 LM2901Q/2903Q series comparators are designed to directly
interface with TTL and CMOS.
The LM2903Q dual devices are available in SO-8, MSOP-8 and
TSSOP-8; and the LM2901Q quad devices are available in SO-14
and TSSOP-14 - all are in industry-standard pinouts.
All use greenmold compound and are qualified to AEC-Q100
Grade 1 and are Automotive Compliant supporting PPAPs.

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
4. Automotive products are AEC-Q100 qualified and are PPAP capable. Refer http://www.diodes.com/quality/product_compliance_definitions/.
