Where is the max output current mentioned for this opamp? What does "Million Min" mean in this context?
And where is the max base current is mentioned for this transistor?
Don't expect the opamp to maintain spec operating at "non-zero" currents
Guaranteed High Gain
5mA Load Current: 1.5 Million Min
17mA Load Current: 0.8 Million Min
means the gain is at least that many million (at a minimum)
For NPN max base current, there is little point exceeding the base current that saturates the collector current, even if it doesn't overheat. The collector current should be dominating the heat dissipated anyways. Base current should be miniscule in comparison.
