In slave mode, the internal timing starts clocking by the rising edge falling edge at mode 1 of LRCK after exiting from reset and power down state by MCLK.

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. The power up sequence between VA and VD is not critical.
The akn and stopband frequencies scale with fs. The AK requires no external components because the analog inputs are single-ended. The cut-off frequency of the HPF is 1. Alternatively if VA and VD are supplied separately, the power up sequence is not critical.
The AK samples the analog inputs at 64fs. Operation at or beyond these limits may result in permanent damage to the device. The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time. No 53811 current may be drawn from these pins.
System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board. The audio interface supports both master a,m slave modes.
All digital input pins should not be left floating. Normal operation is not guaranteed at these extremes. The reference frequency of these responses is 1kHz. Input voltage is proportional to VA voltage.
This reset should always be done after power-up. An analog initialization cycle starts after exiting the power-down mode. Table 1 53381 the relationship of typical sampling 53811 and the system clock frequency. The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs.
Lead frame surface treatment: If these clocks are not provided, the AK may draw excess current due to its use of internal dynamically refreshed logic. Grounding and Power Supply Decoupling The AK requires careful attention to kam supply and grounding arrangements. VA and VD are usually supplied from the analog supply in the system.

An electrolytic capacitor 2. This value is the full scale 0dB of the input voltage.
All voltages with respect to ground. The input signal range scales with the supply voltage and nominally 0. AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
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.
Before considering any use or application, consult the Asahi Kasei Microsystems Co. An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results. In master mode, the internal timing starts when MCLK is input. AKM sales office or authorized distributor concerning their current status.

Date Code Marketing Code: The digital filter rejects noise above the stop band except for multiples of 64fs. This time is from the input of an analog signal to the setting of 24bit data both channels to the ADC output register for ADC. Decoupling 531 should be as near to the AK as possible, with the small value ceramic capacitor being the nearest.
Resolution 24 Bits Input Voltage Note 4 2. The calculated delay time induced by digital filtering. Voltage Reference The voltage input to VA sets the analog input range. All signals, especially clocks, should be kept away akn the VCOM pin in order to avoid unwanted coupling into the AK
