Figure 32. Application Schematic With TPA2031D1 Summing Differential Input and Single-Ended Input
Signals
Four resistors and three capacitors are needed for summing single-ended input signals. The gain and corner
frequencies (fc1 and fc2) for each input source can be set independently (see Equation 11 through Equation 14,
and Figure 33). Resistor, RP, and capacitor, CP, are needed on the IN+ terminal to match the impedance on the
IN– terminal. The single-ended inputs must be driven by low impedance sources even if one of the inputs is not
outputting an ac signal.
