Amm Code Marketing Code: All voltages with respect to ground. 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 calculated delay time induced by digital filtering. An analog initialization cycle starts after exiting the power-down mode. If these clocks are not provided, the AK may draw excess current due to its use of internal qkm refreshed logic. 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 input signal range scales with the supply voltage and nominally 0. Normal operation is not guaranteed at these extremes. VA and VD are usually supplied from the analog supply in the system.

Operation at or beyond these limits may result in permanent damage to the device. The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs. In master mode, the internal timing starts when MCLK is input.

This value is the full scale 0dB of the input voltage. Lead frame surface treatment: The digital filter rejects noise above the stop band except for multiples of 64fs. Table 1 shows the relationship of typical sampling frequency and the system clock frequency. Resolution 24 Bits Input Voltage Note 4 2.

The AK samples the analog inputs at 64fs. No load current may be drawn from these pins.

The reference frequency of these responses is 1kHz. The audio interface supports both master and slave modes.

Decoupling capacitors should be as near to the AK as possible, with the small value ceramic capacitor being the nearest. AKM sales office or authorized distributor concerning their current status. The power up sequence between VA and VD is not critical. System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board. The passband ak stopband frequencies scale with fs. All signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK 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.

All digital input pins should not be left floating.


Voltage Reference The voltage input to VA sets the analog input range. Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements. AKM assumes no responsibility akmm the usage beyond the conditions in this datasheet.

The AK requires no external components because the analog inputs are single-ended. Before considering any use or application, consult 5831 Asahi Kasei Microsystems Co. 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. Input voltage is proportional to VA voltage.

The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time.

This reset should always be done after power-up. An electrolytic capacitor 2. An evaluation board qkm available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results.

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 ak, 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.
