LM2902/ LM2902A/ LM2904/ LM2904A
DUAL AND QUAD OPERATIONAL AMPLIFIERS
Description
The LM2902/2904 series amplifiers consist of four and two
independent high-gain operational amplifiers with very low input offset
voltage specification. They have been 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 LM2902/2904 series are characterized for operation from
-40℃ to +125℃ and the dual devices are available in SO-8, MSOP-8,
TSSOP-8 and the quad devices available in SO-14 and TSSOP-14
with industry standard pin-outs. Both use green mold compound as
standard.

9. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the
output so no loading change exists on the input lines.
10. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (@ +25°C). The upper end of the
common-mode voltage range is V
CC
-1.5V (@ 25°C), but either or both inputs can go to +36V without damage, independent of the magnitude of V
CC
.
11. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can
be detected as this type of capacitance increases at higher frequencies.
12. Typical values are all at T
A
=25°C conditions and represent the most likely parametric norm as determined at the time of characterization. Actual
typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed
on shipped production material.
13. All limits are guaranteed by testing or statistical analysis. Limits over the full temperature are guaranteed by design, but not tested in production.
