Maximum power dissipation, including output load must be designed to maintain the maximum junction temperature below 175oC for Hermetic packages, and below 150oC for the plastic packages. 2. θJA is measured with the component mounted on an evaluation PC board in free air. 3. For differential input voltages greater than 0.7V, the input current must be limited to 25mA to protect the back-to-back input diodes.

Typical range is ±4mV with RT = 10kΩ. FIGURE 3. SUGGESTED OFFSET VOLTAGE ADJUSTMENT CS + R2 R1 - R1 - R3 + R2 R3 C3 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.
