    I need to drive a 5K coil with a single or dual op amp.

    Can anyone provide a brief summary of available design options ranging
    from most to least eficient, and the advantges of each in terms of
    current and voltage swing?

    For example:

    Driving to ground
    Dual drive

    .... and so on. How do these and others compare?

    Thank you,

  5. Gees, JF, have the courtesy to blot out the spammer's referral number
    when you post the followup so that the spamming SOB can't get any
    benefit from your followup.

    In all likelihood, it was an autoposting 'bot that did that, and the
    spammer will never read any followup. Duh.
