Application Information

FIGURE 3. SUGGESTED OFFSET VOLTAGE ADJUSTMENT

NOTE: Low resistances are preferred for low noise applications as a 1k

Ω resistor has 4nV/√Hz of thermal noise. Total resistances of greater than

10k

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

improve stability.
