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.

Voltage Reference The voltage input to VA sets the analog input range. An analog initialization cycle starts after exiting the power-down mode. System analog ground and digital ground should be connected together near to where the supplies are brought onto the printed circuit board. An electrolytic capacitor 2. The cut-off frequency of the HPF is 1. The passband and stopband frequencies scale with fs.

If these clocks are not provided, the AK may draw excess current due to its use of internal dynamically refreshed logic.

VA and VD are usually supplied from the analog supply in the system.

Grounding and Power Supply Decoupling The AK requires careful attention to power supply and grounding arrangements. Resolution 24 Bits Input Voltage Note 4 2. Normal operation is not guaranteed at these extremes.

The AK samples the analog inputs at 64fs. The input signal range scales with the supply voltage and nominally 0. The digital filter rejects noise above the stop band except for multiples of 64fs. The ADC outputs settle in the data corresponding to the input signals after the end of initialization Settling approximately takes the group delay time. AKM assumes no responsibility for the usage beyond the conditions in this datasheet.

In master mode, the 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. Before considering any use or application, consult the Asahi Kasei Microsystems Co. Date Code Akmm Code: The audio interface supports both master and slave modes. No load current may be drawn from these pins.

Input voltage is proportional to VA voltage. AKM sales office or authorized distributor concerning their current status.

The calculated delay time induced by digital a,m. The AK requires no external components because the analog inputs are single-ended. Lead frame surface treatment: The AK includes an anti-aliasing filter RC filter to attenuate a noise around 64fs. 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.

All digital input pins should not be left floating.

An evaluation board is available which demonstrates application circuits, the optimum layout, power supply arrangements and measurement results. This value is the full scale 0dB of the input voltage.

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.

Operation at or beyond these limits may result in permanent damage to the device. All signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK The reference frequency of these responses is 1kHz.

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.
