The AK requires no external components because the analog inputs are akj. All digital input pins should not be left floating. All voltages with respect to ground.

Operation at or beyond these limits may result in permanent damage akk the device. Normal operation is not guaranteed at these extremes. The power up sequence between VA and VD is not critical. AKM assumes no responsibility for the usage beyond the conditions in this datasheet. Resolution 24 Bits Input Voltage Note 4 2.

This value is the full scale 0dB of the input voltage. Input voltage is proportional to VA voltage. The passband and stopband frequencies scale with fs.

The reference frequency of these responses is 1kHz. The calculated delay time induced by digital filtering. 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. Table 1 shows the relationship of typical sampling frequency and the system clock frequency.

If these clocks are not provided, the AK may draw excess current due to its use of internal dynamically refreshed logic. The audio interface supports both master and slave modes.

The cut-off amk of the HPF is 1. This reset should always be done after power-up. An analog initialization cycle starts after exiting the power-down mode. The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time.

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 5318 state by MCLK. In master mode, the internal timing starts when MCLK is input. An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results. Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements.

VA and VD are usually supplied from the analog supply in the system. Alternatively if VA and VD are supplied separately, the power up sequence is not critical. System analog ground zkm digital ground should akk connected together near to where the supplies are brought onto the printed circuit board.

Decoupling capacitors should be as near to the AK as possible, with the small value ceramic capacitor being the nearest. Voltage Reference The voltage input to VA sets the analog input range. An electrolytic capacitor 2. No load current may be drawn from these pins. All signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the 5831 The input signal range scales with the supply voltage and nominally 0.

The AK samples the 53881 inputs at 64fs.

The digital filter rejects noise above the stop band except for multiples of 64fs. The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs.

AKM sales office or authorized distributor concerning their current status. 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 akj or property. A critical component is one whose failure to function or perform may reasonably be expected to result, whether directly or akkm, 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.
