    Device operating voltages and sensor voltages have been reducing over time. This makes noise, an important factor when you work with Opamp. Knowing the changes in Opamp noise density with frequency comes in handy while working with PSoC® Opamp-based designs. A graphical representation is more intuitive and user-friendly for the design process. To help with that - using the point data from the device datasheet and the curve estimated from 1/sqrt(f) noise characteristic, the graph in Figure 1 is generated.
