AKD4387-SB
AK4387 Evaluation board Rev.0
General Description The AKD4387-SB is an evaluation board for AK4387, which is 192kHz sampling 24Bit DAC. The AKD4387-SB includes a LPF which can add differential analog outputs from the AK4387 and also has a digital interface. Therefore, it is easy to evaluate the AK4387.

Evaluation mode
1. DIR (COAX) (default) It is possible to evaluate the AK4387 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through RCA connector (J3). Setting of jumper is shown below. COAX is recommended for an evaluation of the Sound quality.

External Analog Circuit
The 2nd order LPF (fc=125.6kHz, Q=0.753) which adds differential outputs of the AK4387 is implemented on the board. When the further attenuation of the out-band noise is needed, some additional LPF is required. Analog signal is output through BNC connectors on the board. And the output level of the AK4387 is 5.67Vpp@5V.

AKM assumes no liability for infringement of any patent, intellectual property, or other right in the application or use of any information contained herein. Any export of these products, or devices or systems containing them, may require an export license or other official approval under the law and regulations of the country of export pertaining to customs and tariffs, currency exchange, or strategic materials. AKM products are neither intended nor authorized for use as critical components in any safety, life support, or other hazard related device or system, and AKM assumes no responsibility relating to any such use, except with the express written consent of the Representative Director of AKM. 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.
