You rig up both amplifiers as unity gain inverters, and use the output of one amp to drive the inverting input of the other. You have to figure out how to make the +-11V input at 0 volts cause the first amplifier to drive +6 volts (or half of the supply voltage) and reference the other inverting amplifier to half the supply voltage.
BTW... does anyone know of a good ASCII drawing program, so I can easily make drawing that won't get scrubbed by the list software? ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
