LM2902Q/LM2902AQ/LM2904Q/LM2904AQ
AUTOMOTIVE COMPLIANT DUAL AND QUAD OPERATIONAL AMPLIFIERS
Description Pin Assignments
The LM2902Q/2904Q series operational amplifiers consist of four and
LM2904Q/ LM2904QA
two independent high-gain operational amplifiers with very low input
offset voltage specification. They are designed to operate from a
(Top View)
single power supply over a wide range of voltages; however,
operation from split power supplies is also possible. They offer low
1OUT 1 8 VCC
power supply current independent of the magnitude of the power

MSOP-8; and the LM2902Q quad devices are available in SO-14 and 4 5 2IN+
GND
TSSOP-14. All are in industry-standard pinouts, and both use green
mold compound as standard.
SO-8/TSSOP-8/MSOP-8
The LM2902Q/2904Q are characterized for operation from
-40C to +125C, qualified to AEC-Q100 Grade 1 and are Automotive
LM2902Q/ LM2902QA
Compliant supporting PPAPs.
