IN1L Single-Ended vs Fully-Differential Control If IN1L is selected to both left and right ADC
channels, both connections must use the same configuration (single-ended or fully-differential
mode).
0: IN1L is configured in single-ended mode
1: IN1L is configured in fully-differential mode

IN1L Input Level Control for Right ADC PGA Mix
Setting the input level control to a gain below automatically connects IN1L to the right 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
