Pseudo-differential stereo input (IN1)
The IN1- input is implemented as a buffered pseudo-differential stereo stage with 100 kΩ
input-impedance at each input pin. This input is also configurable as single-ended stereo
input. The common input-pin, IN1- features a fast charge switch to speed up the charge time
of external capacitors. This switch is released the first time the input-selector data-byte (0) is
accessed.
