7.4.2.2 VS Referenced Output

Unidirectional mode with a VS referenced output is configured by connecting both reference pins to the positive supply. Use this configuration for circuits that require power up and stabilization of the amplifier output signal and other control circuitry before power is applied to the load (see Figure 7-3).
