... Low Power 20-Bit ADC with MIC-Amp & PGA The AK5356 is a low voltage 20bit A/D converter for digital audio system. The AK5356 also includes microphone amplifier and analog input PGA, making it suitable for microphone applications or low-input signal levels. As digital power supply of the AK5356 corresponds to 1.8V, the interface with microprocessor can operate at low voltage ...

... All external clocks (MCLK, BCLK and LRCK) should always be present whenever the ADC is in operation. If these clocks are not provided, the AK5356 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 AK5356 should be placed in power-down mode ...

... Digital High Pass Filter The AK5356 has a Digital High Pass Filter (HPF) to cancel DC-offset in both the IPGA and ADC. The cut-off frequency of the HPF is 3.4Hz at fs=44.1kHz. This cut-off frequency scales with the sampling frequency (fs). And the HPF can select ON/OFF by HPF bit ...

... ASAHI KASEI n System Reset The AK5356 is placed in the power-down mode by bringing PDN pin “L”. The control registers are 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 clocks. During initialization, the ADC digital data outputs of both channels are forced to a 2’ ...

... The internal registers are written by the 3-wire P interface pins: CSN, CCLK, CDTI. These data are included by Chip Address (2bit, The AK5356 is fixed to “10”.), Read/Write (1bit), Address (MSB-first, 5bit) and Control data (MSB-first, 8bit). A side of transmitted data is output to each bit by “ ” of CCLK, a side of receiving data is input by “ ” of CCLK. ...

... Power OFF 1: Power ON (Default) When PDN pin goes “L”, all circuit in the AK5356 can be powered-down in no relation to PMADC and PMMIC bits. When PMADC and PMMIC bits go “0”, all circuit in the AK5356 can be also powered-down. However, the contents of control registers are held. ...
