The AK4543 can function as a Primary AC’ 97 or Secondary codec depending on the codec ID configuration Multiple codec extension , making the AK4543 suitable for the docking station application and multiple codec applications such as 4 speaker output or 6 speaker output. Sampling at 48kHz, the AK4543 provides excellent audio performance, meeting or exceeding all standard requirements. It offers low power consumption, and flexible power-down modes for use in laptops, desktop PCs, and aftermarket add-in boards. Like the earlier pin-compatible AK4540 and AK4542, the AK4543 is available in a compact 48-lead LQFP package. The AK4543 is a pin compatible upgrade for the AK4540 and AK4542, some software changes will be required to experience the extra functions ot the AK4543.
