Mar 5, 2018 at 2:59 | comment | added | user105652 | Welcome to EE.SE. Well, at least this much works good, so it is best to leave it alone and do the level shifting downstream. Use a DC blocking capacitor, a resistors and diode to get rid of negative voltage. Now you have only 0 to 4 volts to fix. Add a 2.5 volt offset, then subtract 2.75 volts to get 2.25 to 3.25 volts. | |
Mar 5, 2018 at 2:57 | comment | added | Russell Borogove | You can use another op-amp to offset and scale the signal. There's a worksheet here: ti.com/lit/an/sloa097/sloa097.pdf and an online calculator here: daycounter.com/Calculators/Op-Amp/… that might be of use. | |
