Ah. I am getting confused. You don't. That circuit (and the other one I came up with with a pair of optos) only gives you 0 to X volts. I have only ever used it to drive a VFD. +/- 10V is more tricky, (and offset PWM is not a great way to do it). PWM + DIR is a safer approach as then you don't get full-scale at power-off. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
