4.2.1 Line Inputs

For the line input configuration (shown in Figure 4-8), the TAA3020 captures the audio signal provided through terminals J2 (IN1) and J3 (IN2). The input accepted in this mode is a differential, 2-VRMS, full-scale audio signal. If a single-ended source is used, then 1-VRMS signal is supported.
