POWERDOWN SEQUENCE
1.
Mute all outputs:
•
MUTE_ALL=1
2.
Set up biases for power down mode:
•
FAST_EN=1
•
VMID_SEL=01
•
BIAS_EN=1
•
BUFIO_EN=1
•
VMIDTOG=1
•
SOFT_ST=0
3.
Switch outputs to use fast bias instead of master bias:
•
POBCTRL=1
4.
Power down all WM8593 functions (ADC, DACs, PGAs etc.). The outputs are muted so the
write order is not important.
5.
Power down VMID to allow the analogue outputs to ramp gently to ground in a pop-free
manner.
•
VMID_SEL=00
6.
Wait until DACVMID has fully discharged. The time taken depends on system capacitance.
•
Insert delay
7.
Clamp outputs to ground.
•
APE_B=0
8.
Power down outputs.
•
VOUTxL_EN=0
•
VOUTxR_EN=0
9.
Disable remaining bias control bits.
•
FAST_EN=0
•
POBCTRL=0
•
BIAS_EN=0
Power supplies can now be safely removed from the WM8593 if desired. Table 44 describes the
various bias control bits for power up/down control.
