... ASAHI KASEI The AK5358 is a stereo A/D Converter with wide sampling rate of 8kHz consumer to professional audio system. The AK5358 achieves high accuracy and low cost by using Enhanced dual bit techniques. The AK5358 requires no external components because the analog inputs are single-ended. The audio interface has two formats (MSB justified, I various systems like DTV, DVR and AV Receiver ...

... All external clocks (MCLK, SCLK and LRCK) must be present unless PDN pin = “L”. If these clocks are not provided, the AK5358 may draw excess current due to its use of internal dynamically refreshed logic. If the external clocks are not present, place the AK5358 in power-down mode (PDN pin = “L”). In master mode, the master clock (MCLK) must be provided unless PDN pin = “ ...

... ASAHI KASEI T Power down The AK5358 is placed in the power-down mode by bringing PDN pin “L” and the digital filter is also reset at the same time. This reset should always be done after power-up. In the power-down mode, the VCOM are AGND level. An analog initialization cycle starts after exiting the power-down mode. Therefore, the output data SDTO becomes available after 4129 cycles of LRCK clock in master mode or 4132 cycles of LRCK clock in slave mode. During initialization, the ADC digital data outputs of both channels are forced to a 2’ ...

... AGND and DGND of the AK5358 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 AK5358 as possible, with the small value ceramic capacitor being the nearest. ...
