All digital input pins should not be left floating. System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board. The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay kam. Alternatively if VA and VD ajm supplied separately, the power up sequence is not critical.
Resolution 24 Bits Input Voltage Note 4 2.
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. 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.
Date Code Marketing Code: If these clocks are not provided, the AK may draw excess current due to its use of internal dynamically refreshed logic. Table 1 shows the relationship of typical sampling frequency and the system clock frequency.
AKM sales office or authorized distributor concerning their current status. Normal operation is not guaranteed at these extremes. This reset should always be done 53881 power-up. An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results.
AKM assumes no responsibility for the usage beyond the conditions in this datasheet. Decoupling capacitors should be as near to the AK as possible, with the small value ceramic capacitor being the nearest. Lead frame surface treatment: All voltages with respect to ground.
The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs. Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements. The reference frequency of these responses is 1kHz. An analog initialization cycle starts after exiting the power-down mode.
VA and VD are usually supplied from the analog supply in the system. The power up sequence between VA and VD is not critical. A critical akn 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 AK requires no external components because the analog inputs are single-ended. The audio interface supports both master and slave modes. The cut-off frequency of the HPF is 1.
The calculated delay time induced by digital filtering. 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 3581 be expected to result in loss of life or in significant injury or damage to person or property. This value is the full scale 0dB of the input voltage.

Before considering any use or application, consult the Asahi Kasei Microsystems Co. An electrolytic capacitor 2.
Voltage Reference The voltage input to VA sets the analog input range. Input voltage is proportional to VA voltage. All signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK In master mode, the internal timing starts when MCLK is input.
The digital filter rejects noise above the stop band except for multiples of 64fs. No load current may be drawn from these pins. The AK samples the analog inputs at 64fs. Operation at or beyond these limits may result in permanent damage to the device.
The passband and xkm frequencies scale with fs. The input signal range scales with the supply voltage and nominally 0.
