Figure 7. Line Input Block Diagram
The device includes two sets of line inputs (Figure 7).
Each set can be configured as a stereo single-ended
input or as a mono differential input. Each input includes
adjustable gain to match a wide range of input signal
levels. If a custom gain is needed, the external gain
mode provides a trimmed feedback resistor. Set the gain

by choosing the appropriate input resistor and using the
following formula:
The external gain mode also allows summing multiple
signals into a single input, by connecting multiple input
resistors as show in Figure 8, and inputting signals larger
than 1V
