Hi, i'm i've build an circuit, ilustrated in the bellow figure, which its purpose is to sample an Sine Wave of 1kHz sourced by an InAmp (AD8226) with an ADC from a uC (Pic18f26j13) with maximum Fsampling= 40 kHz . This adc has 12 bit and its voltage reference is 3V.
When i designed the following circuit i added an passive anti-aliasing filter but i was reckless and i didn't know very well what i was doing. So i projected with some values that i realize now that were totally wrong and this...
