Tying the SE/BTL and IN2/IN1 Pins Together
In some applications, it may be desirable to have one input specifically for BTL operation and one input specifically for SE
operation. This is accomplished by tying the SE/BTL and IN2/IN1 pins together and connecting them to a common control
voltage. An example of this type of configuration can be found in Figure 22. The two pins are tied together and are
connected to the resistor divider network. That network is connected to the stereo headphone jack, and is closed when
no plug is inserted. This pulls both the IN2/IN1 and SE/BTL pins low, causing the amplifier to go into BTL mode using the
IN1 (RIN1 and LIN1) inputs. Should a headphone plug be inserted into the headphone jack, both inputs would be pulled
high, and the amplifier would be in SE mode using the IN2 inputs.
