The AK4564 16-bit ADC/DAC device from Asahi Kasei Microsystems Co. Ltd uses digital technology during recording to achieve a 30 percent reduction in power consumption compared to the company's previous products.

Suited for use in portable A/V devices and personal electronics applications, the codec also integrates microphone, headphone, and speaker amplifiers, and also offers digital equalizer EQ, selectable high-pass and low-pass filters, fade-in/fade-out functions, power management, and multi-voltage power supply support (2.6V to 5.5V).

The multiple voltage support enables setting the optimum voltage for each block, further reducing power consumption, while improving performance.
