Power Up/Down Sequence

The PAM8620 employs a shutdown operation mode to reduce supply current to the absolute minimum level during periods of non-use to save

power. The SD input terminal should be held high during normal operation when the amplifier is in use. Pulling SD low causes the outputs to

mute and the amplifier to enter a low-current state. SD should never be left unconnected to prevent the amplifier from unpredictable operation.

Suggest PL starting voltage is greater than 5V.

Start-up /power down sequencer recommended.
