Single-ended input configuration
It's possible to use the TS4962 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration. The schematics in
single-ended input typical application.
Figure 61. 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 on both TS4962 inputs (In
