3.1.1 Line Inputs

For the line input configuration, shown in Figure 3-2, the PCM1840 captures the audio signal provided through terminals J1 (IN1), J2 (IN2), J3 (IN3), and J4 (IN4). The input accepted in this mode is a differential, 2 VRMS, full-scale audio signal. Single-ended inputs are not supported by the PCM1840 device and the inputs should be AC coupled.
