the same voltage potential.
Measured using an input signal of 1 V DC.
For optimum performance, VREF+ should always be less than (V+) - 0.2 volts to prevent saturation of the VREF+ input buffer.
Tested with 100 mVp-p on any supply up to 1 kHz. V1+ and V2+ supplies at the same voltage potential, V1- and V2- supplies at
