Figure 17. Power-up/down sequence of ADC
(1) PDN pin should be set to “H” at least 150ns after the power is supplied.
(2) HPLMT, HPRMT and PMVCM bits should be changed to “1” after PDN pin goes to “H”.
(3) PMADC bit should be changed to “1” after HPLMT, HPRMT and PMVCM bits are changed to “1”.
(4) External clocks (MCLK, BICK, LRCK) are needed to operate ADC.
(5) When PMADC bit is changed to “1”, each AIN pin is biased to VCOM voltage. Rising time constant is determined
by input capacitor for AC coupling and input resistance. In case of AINL2/AINR2 and 1μF input capacitor, time
constant is
τ
= 1μF x 12.5k
= 12.5ms (typ)
(6) The analog part of ADC is initialized during 2081/fs(=47ms@fs=44.1kHz) after exiting the power-down state.
SDTO is “L” at that time.
(7) Digital output corresponding to analog input has the group delay (GD) of 17.0/fs(=385μs@fs=44.1kHz).
