This value is the full scale 0dB of the input voltage. The reference frequency of these responses is 1kHz. No load current may be drawn from these pins. The audio interface supports both master and slave modes.

An electrolytic capacitor 2. Table 1 shows the relationship of aakm sampling frequency and the system clock frequency. Decoupling capacitors should be as near to the AK as possible, with the small value ceramic capacitor being the nearest.

Alternatively if VA and VD are supplied separately, the power up sequence is not critical. 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. The power up sequence between VA and VD is not critical.

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.

Resolution 24 Bits Input Voltage Note 4 2.

The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time. The AK requires no external components because the analog inputs are single-ended. An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results.

The digital filter rejects noise above the stop band except for multiples of 64fs. AKM assumes no responsibility for the usage beyond the conditions in this datasheet. Operation at or beyond these limits may result in permanent damage to the device. Input voltage is proportional to VA voltage. This reset should always be done after power-up.

Before considering any use or application, consult the Asahi Kasei Microsystems Co. The AK samples the analog inputs at 64fs. All signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK The passband and stopband frequencies scale with fs.

Normal operation is not 531 at these extremes.

The cut-off frequency of the HPF is 1. AKM sales office or authorized distributor concerning their current status. In master mode, wkm internal timing starts when MCLK is input. 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.

Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements. Voltage Reference The voltage input to VA sets the analog input range. Date Code Marketing Code: System analog ground and 531 ground should be connected together near to where the supplies are brought onto the printed circuit board.

All digital input pins should not be left floating. The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs. 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.

All voltages with respect to ground.

The calculated delay time induced by digital filtering.
