2.2.2.1 Line Inputs

For the line input configuration (shown in Figure 3-9), the PCMx140Q1 captures the audio signal provided through terminals J2 (IN1), J3 (IN2), J4 (IN3), and J5 (IN4). The input accepted in this mode is a differential, 2-VRMS, full-scale audio signal. If a single-ended source is used, the 1-VRMS signal is supported.
