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 and the

quad devices available in SO-14 and TSSOP-14 with industry

standard pin-outs. Both use green mold compound as standard.

 Halogen and Antimony Free. “Green” Device (Note 3)

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.

Notes: 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

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

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.
