Hi Team,

Please help me answer the follow question from my customer, thank you so much.

We can't find the term of source current and sink current of those products.
Also we can't find the term of voltage gain.
Please let us know the information above mentioned.

Best Regards,
Tom Liu

    Hi Liu,

    The voltage gain can be found on the second page of the datasheet as Avd.

    We will look into the current source/sink capabilities of the LF411.

    Thank you,

    Tim Claycomb

    Hello Liu,

    I have data for LF412CN which will be similar to the LF411CP and LF411CN which are based on the same design.

    VOL and VOH (in volts) versus output current with a +/-5V supply. VOL is negative and VOH is positive voltage. 

    VOL and VOH versus output current with a +/-15V supply.

    Both look the same as output drive works the same regardless of the supply voltage
