General Description
The AK4544A is a 18bit high performance codec which support
variable sampling rate conversion compliant with Audio Codec ’ 97
Rev 2.1 requirements.
The AK4544A 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 AK4544A
has the POP feature suitable for 3D positioning and direct output from
DAC for AD monitoring or docking station application.
The AK4544A can function as a Primary AC’ 97 or Secondary codec
depending on the codec ID configuration(Multiple codec extension),
making the AK4544A suitable for the docking station application and
multiple codec applications.
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 AK4544A 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 AK4540, AK4541, AK4542, and
AK4543, the AK4544A is available in a compact 48-lead LQFP
package.
