... Single bit way. The AK5351 is suitable for digital surround and Hi-Fi audio application such as Car-audio, MD, etc. Analog inputs of the AK5351 are normally Full-differential inputs, while they are also acceptable Single-ended inputs. The AK5351 is available in a small 24pin VSOP package which will reduce your system space. Full-differential / Single-ended inputs S/(N+D): 97dB ...

... The AK5351 has a Digital High Pass Filter(HPF) for DC-offset cancel. When HPFE pin goes "H", HPF is enabled. The cut-off frequency of the HPF is 1Hz(@fs=48kHz). It also scales with the sampling frequency(fs). The HPF can be disabled by bringing HPFE pin "L". In this case, the AK5351 has the DC-offset of a few mV. 0166-E-00 ...

... NOTE: +5V Analog should be powered the same time or earlier than +5V Digital. Grounding and Power Supply Decoupling The AK5351 requires careful attention to power supply and grounding arrangements. The VA and VB are connected together through the chip substrate and have several ohm resistance. The power to VB should come up at the same time or faster than the power to VD, when they are fed separately to the device (Figure 5) ...

... VREF and the VA pins. No current should be driven from the VREF pin. The AK5351 accepts +5V supply voltage. Any voltage which exceeds the upper limit of (VA+)+0.3V and lower limit of AGND-0.3V and any current beyond 10mA for the analog input pins(AINL±, AINR±) should be avoided. ...

... To minimize digital originated noise, connect the ADC digital outputs only to CMOS inputs. Logic families of 4000B, 74HC, 74AC, 74ACT and 74HCT series are suitable. Multiple AK5351 In systems where multiple ADC's are required, care must be taken to insure the internal clocks are synchronized between converters to make simultaneous sampling. In slave mode, synchronous sampling is achieved by supplying the same MCLK and LRCK to all converters ...
