Can someone help me to clarify this ?
Input voltage noise of the op-amp
Your op-amp has an input noise voltage of typically 1.1 \$\text{nV/}\sqrt{Hz}\$. Your noise bandwidth is 50 kHz x 1.57 (for a simple RC low pass filter). Hence the equivalent noise at your input is: -
$$1.1 \text{nV} \times \sqrt{50,000 \times 1.57} = 308 \text{ nV RMS}$$
Multiply this ...
