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.
All formulas are identical except for the gain with R
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
