• Description: 4-Channel ADC with PLL & MIC-AMP
• Manufacturer: AKM [Asahi Kasei Microsystems]

MS0623-E-00
Power Supply
PMVCM bit
(Addr:00H, D2)
4. EXT Slave Mode
<Example>
LRCK pin
BCLK pin
MCKI pin
PDN pin
(1) After Power Up: PDN pin “L” → “H”
(2) DIF1-0 and FS1-0 bits should be set during this period.
(3) Power Up VCOM: PMVCM bit = “0” → “1”
(4) Normal operation starts after the MCKI, LRCK and BCLK are supplied.
“L” time of 150ns or more is needed to reset the AK5702.
VCOM should first be powered up before the other block operates.
