ASAHI KASEI [AK4586] MS0097-E-01 2001/12 - 1 - GENERAL DESCRIPTION The AK4586 is a single chip CODEC that includes two channels of ADC and six channels of DAC. The ADC outputs 24bit data and the DAC accepts up to 24bit input data. The ADC has the Enhanced Dual Bit architecture with wide dynamic range. The DAC introduces the new developed Advanced Multi-Bit architecture, and achieves wider dynamic range and lower outband noise. The AK4586 also has a digital audio receiver (DIR) compatible with 96kHz, 24bits. The AK4586 can automatically detect a Non-PCM bit stream. The digital audio output can be selected from the ADC output or the digital input. Control may be set directly by programmed through a separate serial interface. The AK4586 has a dynamic range of 100dB for ADC, 106dB for DAC and is well suited for digital surround for home theater and car audio. The AK4586 also has the balance volume control corresponding to the AC-3 system. The AK4586 is available in a small 44pin LQFP package which will reduce system space. *AC-3 is a trademark of Dolby Laboratories.

ASAHI KASEI [AK4586] MS0097-E-01 2001/12 - 52 - 1. Grounding and Power Supply Decoupling The AK4586 requires careful attention to power supply and grounding arrangements. AVDD, DVDD and PVDD are usually supplied from analog supply in system. Alternatively if AVDD, DVDD and PVDD are supplied separately, the power up sequence is not critical. AVSS, DVSS and PVSS of the AK4586 must be connected to analog ground plane. System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board. Decoupling capacitors should be as near to the AK4586 as possible, with the small value ceramic capacitor being the nearest. 2. Voltage Reference Inputs The voltage of VREFH sets the analog input/output range. VREFH pin is normally connected to AVDD with a 0.1µF ceramic capacitor. VCOM is a signal ground of this chip. An electrolytic capacitor 2.2µF parallel with a 0.1µF ceramic capacitor attached to VCOM pin eliminates the effects of high frequency noise. No load current may be drawn from VCOM pin. All signals, especially clocks, should be kept away from the VREFH and VCOM pins in order to avoid unwanted coupling into the AK4586. 3. Analog Inputs ADC inputs are single-ended and internally biased to VCOM. The input signal range scales with the supply voltage and nominally 0.6 x VREFH Vpp (typ). The ADC output data format 2’s compliment. The DC offset is removed by the internal HPF. The AK4586 samples the analog inputs at 64fs. The digital filter rejects noise above the stop band except for multiples of 64fs. The AK4586 includes an anti-aliasing filter (RC filter) to attenuate a noise around 64fs. 4. Analog Outputs The analog outputs are also single-ended and centered around the VCOM voltage. The input signal range scales with the supply voltage and nominally 0.6 x VREFH Vpp. The DAC input data format is 2’s complement. The output voltage is a positive full scale for 7FFFFFH(@24bit) and a negative full scale for 800000H(@24bit). The ideal output is VCOM voltage for 000000H(@24bit). The internal analog filters remove most of the noise generated by the delta-sigma modulator of DAC beyond the audio passband. DC offsets on analog outputs are eliminated by AC coupling since DAC outputs have DC offsets of a few mV.
