Re: Driving ADC, please help

Hi Ramon,

You could use a basic inverting opamp config with the ADA4841-1

Rin would be twice Rf. You could use 5V and ground as the supplies. However the limitations are you may lose some range near ground and near 5V (maybe 50-100mV depending on head/footroom spec). Also the input impedance is dictated by Rin, so not a high impedance input. Is the positive supply fixed at 12V?

Best Rgds,
