Hi Team,
In the circuit below, it is a non-inverting adder configuration of the op-amp. The R148 and R151 form a voltage divider to my input signal +/-5V sine signal to bring it to a level of +/-1.5V sine signal. A 1.5V is added to the +/-1.5V at the noninverting terminal op-amp. The second op-amp is used as a buffer for the reference voltage of 1.5V.
Is there any issue with the setup?.
My doubt is will the 1.5V reference voltage affect my incoming signal.
My input signal +/-5V will be directly fed to an ADC and at the same time, I'm reading this signal through a controller. This voltage divider and adder setup are set to bring the incoming signal down to the input range of my controller.
