Single ended input configuration

It's possible to use the TS4962M in a single-ended input configuration. However, input coupling

capacitors are needed in this configuration. The following schematic shows a single ended

input typical application.

And, due to the internal resistor tolerance we have:

In the event that multiple single-ended inputs are summed, it is important that the impedance
