NOTES:

1. All voltages are referenced to ground.

2. Resistor inputs cannot exceed the substrate bias voltage in the negative direction.

3. Measured with a load as shown in Figure 8.

4. Over a frequency range of 0 - 1 kHz.

5. Load is RL = 600 ΩCL = 10 pF.

6. VDD = +5.0V VB = -5.0V connected as voltage follower with 10V step input and RL = ∞.

7. To achieve best op amp performance, VDD = +5.0V VB = -5.0V and analog ground = 0V. In general

analog ground = VDD + VB .

8. OP AMPS idle, no load.

9. Valid at 25°C only.
