Table 27. Page 0 / Register 21: LINE1R to Left ADC Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 LINE1R Single-Ended vs Fully Differential Control
If LINE1R is selected to both left and right ADC channels, both connections must use the same
configuration (single-ended or fully differential mode).
0: LINE1R is configured in single-ended mode
1: LINE1R is configured in fully differential mode
D6–D3 R/W 1111 LINE1R Input Level Control for Left ADC PGA Mix
Setting the input level control to a gain below automatically connects LINE1R to the left ADC
PGA mix
0000: Input level control gain = 0.0 dB
0001: Input level control gain = –1.5 dB
0010: Input level control gain = –3.0 dB
0011: Input level control gain = –4.5 dB
0100: Input level control gain = –6.0 dB
0101: Input level control gain = –7.5 dB
0110: Input level control gain = –9.0 dB
0111: Input level control gain = –10.5 dB
1000: Input level control gain = –12.0 dB
1001–1110: Reserved. Do not write these sequences to these register bits
1111: LINE1R is not connected to the left ADC PGA
D2–D0 R 000 Reserved. Write only zeros to these register bits.

1111: LINE1R is not connected to the right ADC PGA
D2 R/W 0 Right ADC Channel Power Control
0: Right ADC channel is powered down
1: Right ADC channel is powered up
D1–D0 R/W 00 Right ADC PGA Soft-Stepping Control
00: Right ADC PGA soft-stepping at once per Fs
01: Right ADC PGA soft-stepping at once per two Fs
10-11: Right ADC PGA soft-stepping is disabled
