Bias Current Confusion
Hi all.
I’ve just been looking through the data sheet and application note 1645 "Driving a MOSFET Output stage" for the lm4702. In the data sheet is states that the maximum output current (with the pins shorted) is ~5mA. But it doesn’t seem to say anywhere what it is under normal conditions. I.e. driving a BJT etc. Also, in the application note it talks about 500mA bias current. I was under the impression it could only provide a couple of mAs? Can anyone clear this up for me? Thanks. |
