Single-ended input configuration
It is possible to use the TS4962 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration.
input application.

All formulas are identical except for the gain with R
Due to the internal resistor tolerance we have:
In the event that multiple single-ended inputs are summed, it is important that the
impedance on both TS4962 inputs (In
