Hi,
We are planning to implement this IC to receive I2S signals from an NVIDIA Orin NX. The device will operate in Mono (PBTL) mode to drive a 35W speaker.
Regarding the PDN (Power Down) pin, there are specific power-up and power-down timing requirements. While we are currently planning to use hardware-based control, we are still evaluating how to ensure the PDN pin is pulled low before the main power supply is shut off.
Are there alternative control methods—such as software-based control or other strategies—that you would recommend? Additionally, what are the key considerations we should keep in mind for the circuit design? We are currently in the schematic capture phase.
Thanks!
Jeff
