Installation
CAUTION
All speaker outputs are biased at Vcc/2 and may not be connected to ground
(e.g., through an oscilloscope ground).
Loudspeaker connections vary by device setup. Consult the quick-start guide ( Section 7 ) for more details.
However, the following is a general guideline:
When connecting a speaker in BTL mode, connect the speaker’s two terminals (“+” and “-“) across two
outputs on the TAS5706EVM2. Ensure that the jumper (JP1 - JP4) on each output is in place.
When connecting a speaker in Single-Ended (SE) mode, connect the speaker’s “+” terminal to one EVM
output, and the speaker’s “–“ terminal must be grounded at the output power ground (next to PVCC on the
MC-57xxPSIA). Ensure that the jumper (JP1 - JP4) on each output is removed.
Speakers or loads can be connected to the outputs A-D with clip leads, or cables can be made with
female connectors (JST VHR-2N) that can mate to male connectors on the EVM board.
