7.4.1 Shutdown Mode

For proper shutdown mode operation, the amplifier enable (AMP_EN) pin must be asserted to the desired voltage. An internal pullup resistor is provided on the AMP_EN pin so that if the pin is floated, then the device defaults to an ON state. For applications that require the device to be constantly powered on when the supplies are present, tie the AMP_EN pin to the positive supply voltage (VS+).

The disable operation is referenced from the positive supply. For an OFF state condition, the disable control pin must be 2 V below the positive supply.
