... ASAHI KASEI The AK5359 is a stereo A/D Converter with wide sampling rate of 8kHz ∼ 216kHz and is suitable for consumer to professional audio system. The AK5359 achieves high accuracy and low cost by using Enhanced dual bit ∆Σ techniques. The AK5359 requires no external components because the analog inputs are single-ended ...

... All external clocks (MCLK, SCLK and LRCK) must be present unless PDN pin = “L”. If these clocks are not provided, the AK5359 may draw excess current due to its use of internal dynamically refreshed logic. If the external clocks are not present, place the AK5359 in power-down mode (PDN pin = “L”). In master mode, the master clock (MCLK) must be provided unless PDN pin = “ ...

... ASAHI KASEI Power down The AK5359 is placed in the power-down mode by bringing PDN pin “L” and the digital filter is also reset at the same time. This reset should always be done after power-up. In the power-down mode, the VCOM are AGND level. An analog initialization cycle starts after exiting the power-down mode. Therefore, the output data SDTO becomes available after 4129 cycles of LRCK clock in master mode or 4132 cycles of LRCK clock in slave mode. During initialization, the ADC digital data outputs of both channels are forced to a 2’ ...

Digital 3.3V + 10u 0.1u Note: - AGND and DGND of the AK5359 should be distributed separately from the ground of external digital devices (MPU, DSP etc.). - All digital input pins should not be left floating. - The CKS1 pin should be connected AGND. Digital Ground System Controller Note: - AGND and DGND must be connected to the same analog ground plane ...

... The internal HPF removes the DC offset. The AK5359 samples the analog inputs at 64fs (@fs=48kHz, 96kHz) or 32fs(@192kHz). The digital filter rejects noise above the stop band except for multiples of 64fs or 32fs. The AK5359 includes an anti-aliasing filter (RC filter) to attenuate a noise around 64fs or 32fs. ...
