NOTE: Low resistances are preferred for low noise applications as a 1kΩ resistor has 4nV/√Hz of thermal noise. Total resistances of greater than

10kΩ on either input can reduce stability. In most high resistance applications, a few picofarads of capacitance across the feedback resistor will

improve stability.
