The AK4545 supports S/PDIF output that is digital audio transmitter of IEC958. Audio digital data in PC can be output by this S/PDIF out. The AK4545 provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. In addition, the AK4545 has the POP feature suitable for 3D positioning and direct output from DAC for AD monitoring. Sampling frequency is programmable through AC-link as 48k, 44.1k, 32k, 22.05k, 16k, 11.025k, and 8kHz. This setting is done independent to ADC and DAC side while L/R channels are kept identical. The AK4545 provides excellent audio performance, meeting or exceeding PC99 requirements for a PCI audio solution. It has low power consumption, and flexible power-down modes for use in laptops as well as desktop PCs and aftermarket add-in boards. Like the earlier pin-compatible AK4541, AK4543 and AK4544A , the AK4545 is available in a compact 48-lead LQFP package.
