Ground: Ground for negative PWM speaker driver.
SP-: Negative signal of the differential Class-D PWM speaker outputs. This output,
together with the SP+, is used to drive an 8Ω speaker directly.
Speaker Power Supply: Power supply for PWM speaker drivers.
SP+: Positive signal of the differential Class-D PWM speaker outputs. This output,
together with the SP-, is used to drive an 8Ω speaker directly.
Ground: Ground for positive PWM speaker driver.
