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 R

= 600 Ω C

= 10 pF

6. V

= +5.0V V

= -5.0V connected as voltage follower with 10V step input and R

= ∞.

7. To achieve best op amp performance, V

= +5.0V V

= -5.0V and analog ground = 0V. In general analog

ground =
