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.

Notes:

4. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only; functional

 

 

operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to

 

 

absolute-maximum-rated conditions for extended periods may affect device reliability.

 

 

5.Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of +150°C can affect reliability.

6.Maximum power dissipation is a function of TJ(max), θJC, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of +150°C can affect reliability.

7.Short circuits from outputs to VCC or ground can cause excessive heating and eventual destruction.

8.Human body model, 1.5kΩ in series with 100pF.

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 VCC -1.5V (@ 25°C), but either or both inputs can go to +36V without damage, independent of the magnitude of VCC.

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 TA=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.
