ASAHI KASEI [AKD4528] AKD4528 Evaluation board AK4528 Rev.C GENERAL DESCRIPTION The AKD4528 is an evaluation board for the AK4528, the 24Bit A/D & D/A converter. The AKD4528 can evaluate A/D converter and D/A converter separately in addition to Loopback mode (A/DD/A). The AKD4528 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. n Ordering guide AKD4528 --Evaluation board for AK4528 (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this.)

Analog Input Buffer Circuit The ADC inputs are full differential and the input resistance is 27k (typ. @fs=44.1kHz). The input signal range scales with the VREF voltage and nominally 0.56 x VREF Vpp. It is recommended that the input DC bias voltage is 2.9V(The bias is a voltage divided by resistors (3.3k and 4.7k) from VA in figure 2. The ADC output data format is 2's complement. The output code is 7FFFFFH(@24bit) for input above a positive full scale and 800000H(@24bit) for input below a negative fill scale. The ideal code is 000000H(@24bit) with no input signal. The DC offset including ADC own DC offset removed by the internal HPF (fc=0.9Hz@fs=44.1kHz). The AK4528 samples the analog inputs at 64fs. The digital filter rejects noise above the stopband except for multiples of 64fs. A simple RC filter may be used to attenuate any noise around 64fs though most audio signals do not have significant energy at 64fs. Figure 2 is an example of differential input circuit. 5.96Vpp 4.7k 2.8Vpp 4.7k 330 330 AINR3 2.8Vpp 4.7k + NJM5532 Vop+ 10k + VA Vop3.3k AINL+ 4 AINL5 Vop+/-=+/-15V VA=5V Same circuit BIAS 4.7k + 10u 0.1u 22u Signal AK4528 AINR+ 2 1.5nF Input RC filter response : fc = 160kHz, g = -0.07dB at 20kHz, -0.26dB at 40kHz. Figure 2. Differential Input Buffer Example 2.Analog Output Buffer Circuit The 2nd-order LPF (fc=93.2kHz, Q=0.712) which adds differential output of AK4528 is implemented on the board. When the further attenuation of the out-band noise is needed, some additional LPF is required. NJM5532D is used for op-amp. Analog signal is output through BNC connectors (AOUTL, AOUTR) on board, and the output level of AK4528is about 5.4Vp-p. 4.7k AOUT200 470p 4.7k 3300p 4.7k AOUT+ 4.7k 470p 200 +Vop + -Vop Analog Out fc=93.2kHz, Q=0.712, g=-0.1dB at 40kHz Figure 3.

As used here: (a) A hazard related device or system is one designed or intended for life support or maintenance of safety or for applications in medicine, aerospace, nuclear energy, or other fields, in which its failure to function or perform may reasonably be expected to result in loss of life or in significant injury or damage to person or property. (b) A critical component is one whose failure to function or perform may reasonably be expected to result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or system containing it, and which must therefore meet very high standards of performance and reliability. * It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or otherwise places the product with a third party to notify that party in advance of the above content and conditions, and the buyer or distributor agrees to assume any and all responsibility and liability for and hold AKM harmless from any and all claims arising from the use of said product in the absence of such notification.
