Operation at or beyond these limits may result in permanent damage to the device. This reset should always be done after power-up. An electrolytic capacitor 3581. AKM assumes no responsibility for the usage beyond the conditions in this datasheet.

The power up sequence between VA and VD is not critical. Voltage Reference The voltage input to VA sets the analog input range. Input voltage is proportional to VA voltage. No load current may be drawn from these pins. The input signal range scales with the supply xkm and nominally 0. Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements. System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board.

Normal operation is not guaranteed at these extremes. Before considering any use or application, consult the Asahi Kasei Microsystems Co. The calculated delay time induced by digital filtering. In slave mode, the internal timing starts clocking by the rising edge falling edge at mode 1 of LRCK after exiting a,m 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. An analog initialization cycle starts after exiting the power-down mode. Decoupling capacitors should 5831 as near to the AK as possible, with the small value ceramic capacitor being the nearest.

If these clocks are not provided, the AK may draw excess current due to its use of internal dynamically refreshed logic. AKM sales office or authorized distributor concerning their current status. This value is the full scale 0dB of the input voltage.

The AK requires no external components because the analog inputs are single-ended. Alternatively if VA and VD are supplied separately, the power up sequence is not critical.

The passband and stopband frequencies scale with fs. In master mode, the internal timing starts when MCLK is input. The audio interface supports both master and slave modes. VA and VD are usually supplied from the analog supply in the system. All digital input pins should not be left floating. Lead frame surface treatment: All voltages with respect to ground. Resolution 24 Bits Input Voltage Note 4 2.

All signals, especially clocks, 3581 be kept away from the VCOM pin aim order to avoid unwanted coupling into the AK Date Code Marketing Code: 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.

The reference frequency of these responses is 1kHz. The cut-off frequency of the HPF is 1. An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results. Table 1 shows the relationship of typical sampling frequency and the system clock frequency. The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time.

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, amk which its failure to function or perform may reasonably be expected to result in loss of life or 5318 significant injury or damage to person or property. 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 531 performance and reliability.

The AK samples the analog inputs at 64fs.
