I'm using TAS5414C-Q1 IC for audio amplifier. It has 4 channel analog inputs. I'd like to interface 2 channels from a 3.5 mm jack to these 4 channel inputs. How do I achieve this. Should I parallel the inputs. Is the below pic right way to connect in this regard?
A 3.5mm jack has two channels and a common ground. The datasheet for the amplifier IC shows a series input capacitor for each input (you have none) plus a capacitor from ground of the signal source to pin 18 called IN_M.
You do not show the ground of the jack connected with a series capacitor to the amplifier IC.
The datasheet says the maximum input is 1.9V RMS which is 5.37V p-p.
