Coil driver efficiency

[Jeff]

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
Bridge
Push/pull
VCSS

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

Thank you,

Jeff

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.
