Audio ADC has professional aspirations
The AK5359 is a low-cost high-quality audio A/D convertor for audio applications in professional, consumer equipment and automotive markets.
The AK4396 features dynamic range performance of 120dB.
In addition to excellent antijitter characteristics, the switched capacitor DAC incorporates AKM's unique low-power circuits, which maintain high performance with a very low power consumption of 180mW.
Features of the AK4396 include a dedicated input port for direct stream digital (DSD) data input, allowing switching on the DAC side between PCM data and DSD data.
A built-in lowpass filter dedicated to DSD data allows the SACD format "Scarlet book" filter characteristics to be achieved easily by adding a simple external analogue filter.
The same output level is set for both PCM data and DSD data; so that digital volume control and zero detect functions behave in the same way for both PCM data and DSD data.
This has the advantage of permitting control of playback levels irrespective of the data format, and together with the other performance enhancements, makes the AK4396 ideal for professional-quality DVD/DVD-audio/SACD players, AV receivers and digital mixers.
The AK4396 is available in a 28-pin VSOP package, and is priced at $2.60 in 1000 unit quantities.
Pin compatibility with the AK4393/4 provides a simple upgrade path for AK4393/4-based systems.
Evaluation boards and samples are available now.
