4. Measured using an input signal of 1 V DC.

5. For optimum performance, VREF+ should always be less than (V+) - 0.2 volts to prevent saturation of the VREF+ input buffer.

6. Tested with 100 mVP-P on any supply up to 2 kHz. V1+ and V2+ supplies at the same voltage potential, V1- and V2- supplies at

the same voltage potential.
