... ASAHI KASEI The AK5355 is a low voltage 16bit A/D converter for digital audio systems. The AK5355 also includes an Input Gain Amplifier, making it suitable for microphone applications or low-input signal levels. The analog signal input of the AK5355 is single-ended, eliminating the need for external filters. The AK5355 is housed in a space-saving 16pin TSSOP or 20pin QFN package ...

... All external clocks (MCLK, BCLK and LRCK) should always be present whenever the ADC is in operation. If these clocks are not provided, the AK5355 may draw excess current and will not operate properly because it utilizes these clocks for internal dynamic refresh of registers. If the external clocks are not present, the AK5355 should be placed in power-down mode. ...

... Power down The AK5355 is placed in the power-down mode by bringing PDN “L”. The digital filter is also reset at the same time. This reset should always be done after power-up. An analog initialization cycle starts after exiting the power-down mode. The output data SDTO becomes available after 4128 cycles of LRCK clock. During initialization, the ADC digital data outputs of both channels are forced to a 2’ ...

... In Figure 9, 1 power supply and the microphone. The AK5355 has a gain of +15dB in analog stage. However, as the usual application needs a gain of around 40dB or 50dB, the shortage of gain, 25dB or 35dB, should be covered by digital processing like DSP. The total S/N in each gain level is shown in Table 3 ...
