Page 0 / Register 40: High Power Output Stage Control Register
READ/ RESET
BIT DESCRIPTION
WRITE VALUE
D7 – D6 R/W 00 Output Common-Mode Voltage Control
00: Output common-mode voltage = 1.35 V
01: Output common-mode voltage = 1.5 V
10: Output common-mode voltage = 1.65 V
11: Output common-mode voltage = 1.8 V
D5 – D4 R/W 00 LINE2L Bypass Path Control
00: LINE2L bypass is disabled
01: LINE2L bypass uses LINE2LP single-ended
10: LINE2L bypass uses LINE2LM single-ended
11: LINE2L bypass uses LINE2LP/M differentially
D3 – D2 R/W 00 LINE2R Bypass Path Control
00: LINE2R bypass is disabled
01: LINE2R bypass uses LINE2RP single-ended
10: LINE2R bypass uses LINE2RM single-ended
11: LINE2R bypass uses LINE2RP/M differentially
D1 – D0 R/W 00 Output Volume Control Soft-Stepping
00: Output soft-stepping = one step per f
S
01: Output soft-stepping = one step per 2 f
S
10: Output soft-stepping disabled
11: Reserved. Do not write this sequence to these register bits.
Page 0 / Register 41: DAC Output Switching Control Register
READ/ RESET
BIT DESCRIPTION
WRITE VALUE
D7 – D6 R/W 00 Left DAC Output Switching Control
00: Left DAC output selects DAC_L1 path
01: Left DAC output selects DAC_L3 path to left line output driver
10: Left DAC output selects DAC_L2 path to left high power output drivers
11: Reserved. Do not write this sequence to these register bits.
D5 – D4 R/W 00 Right DAC Output Switching Control
00: Right DAC output selects DAC_R1 path
01: Right DAC output selects DAC_R3 path to right line output driver
10: Right DAC output selects DAC_R2 path to right high power output drivers
11: Reserved. Do not write this sequence to these register bits.
D3 – D2 R/W 00 Reserved. Write only zeros to these bits.
D1 – D0 R/W 00 DAC Digital Volume Control Functionality
00: Left and right DAC channels have independent volume controls
01: Left DAC volume follows the right channel control register
10: Right DAC volume follows the left channel control register
11: Left and right DAC channels have independent volume controls (same as 00)
