Features

The a 18bit high performance codec compliant with Audio Codec '97 Rev 2.1 requirements. The AC Link serial interface allows the to be used with digital controllers as well as custom logic accelerators to meet PC98 and PC99 requirements for a PCI audio solution. The AK4541 provides two pairs of stereo outputs with independent volume controls along with a mono output, multiple stereo and mono inputs, are combined to create flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. The AK4541 can function as a Primary AC'97 or Secondary codec depending on the codec ID configuration(Multiple codec extension), making the AK4541 suitable for the docking station application and multiple codec applications such as 4 speaker output or 6 speaker output. Sampling at 48kHz, the AK4541 provides excellent audio performance. It offers extreme low power consumption, and flexible power-down modes for use in Sub-NoteBook, laptops, desktop PCs, and aftermarket add-in boards. Like the earlier pin-compatible AK4540, AK4542 and AK4543, the AK4541 is available in a compact 48-lead LQFP package. The is a pin compatible upgrade for the AK4540, AK4542 and AK4543, some software changes will be required to experience the extra functions ot the AK4541.
