1. I have application where input signal voltage varies from +5V to -5V. Have to level shift the signal and fed it to microcontroller adc which is sampling at 1MSPS. Microcontroller adc range varies from 0V to 3.3V
Selected OPA316 for this application. Attached find the circuit.
2. Can I level shift the signal using single supply opamp(3.3V) volt from +-5V to 0-3.3Vdc
3. I have calculated resistor values as in attached ckt. I dont have opamp right now, but if I simulate the resistor network without opamp, on applying +5V at vin, I got +3.3V at In+ & on applying -5V at Vin, I get 0V at In+.
4. Is this ckt ok? What error margin I should take for voltage range?
i think 1% resistor values will be ok.
