3.3.2.1S1 — Shutdown Switch

Pushbutton switch S1 on the EVM allows the manual shutdown of the TPA6011A4 amplifier IC.

3.3.2.2J1 — Output Mode Jumper

To keep the module amplifier IC in the single-ended output mode regardless of the module control input state, set jumper J1 to ON.

Jumper J1 connects the SE/BTL output mode control input pin on the amplifier IC directly to VDD, so that when J1 is ON, the IC is held in the single-ended

output mode regardless of the state of the SE/BTL module control input. When J1 is OFF, a pulldown resistor on the module holds the IC output mode control input pin low, keeping the IC in the BTL output mode.

The TPA6011A4 amplifier IC has two separate inputs for each channel. An internal multiplexor selects which input to connect to the amplifier based on the state of the SE/BTL pin on the IC.
