    Hi Peter,

    The number (3) refers to the Large signal voltage gain spec in the EC table for Vs = +/-15V and Vs = +/-5V. The highlights mainly refer to the total output swing at which the large signal voltage gain is measured at for the respective supply voltages.

    Best Regards,

    Rohit

    Hi Peter,

    Would it be possible for you to further explain in detail the customer's issue and setup? Are they unable to see any voltage at the LM7171 output? What is the input voltage before R40?

    Best Regards,
    Rohit
