Figure 40. TPA0232 Example Input MUX Circuit
The TPA0232 offers the capability for the designer to use separate headphone inputs (RHPIN, LHPIN) and line
inputs (RLINEIN, LLINEIN). The inputs can be different if the input signal is single-ended. If using a differential
input signal, the inputs must be the same because the inputs share a common RIN, LIN. Although the typical
application in Figure 31 shows the input mux control signal HP/LINE tied to SE/BTL, that configuration is not
required. The input mux can be used to select between two inputs that are used in both SE and BTL modes.
If using the TPA0232 with a single-ended input, the RIN and LIN terminals must be tied through a capacitor to
ground, as shown in Figure 40. RIN and LIN must not be tied to bypass or an offset occurs on the output causing
the device to pop when turning on and off.
Input coupling capacitors can be eliminated when using differential inputs, but are used to obtain maximum
output power. If the input capacitors are eliminated, the dc offset must match the voltage on BYPASS or the
output power is limited.
