Loudspeaker Connectors
CAUTION
All BTL speaker outputs are biased at Vcc/2 and must not be connected to
ground (e.g., through an oscilloscope ground).
Loudspeaker connections vary by device setup. When connecting a speaker in single-ended mode,
connect the positive terminal to one output on the TAS5711EVM (A, B, C, or D), and connect the negative
terminal to ground. When connecting a speaker in BTL mode, connect the speaker’s two terminals across
two outputs on the TAS5711EVM (A and B or C and D).
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.

USB Interface
The TAS5711 registers are accessed through I 2 C? bus lines SDA and SCL. The USB circuit and USB
connector on the MC57xxPSIA board facilitates the connection between a host computer and the device.
The EVM USB circuit is powered by the 5-V USB line of the host PC and is independent of the power
supplies available on the board. The USB device that is used is a TAS1020B from Texas Instruments.
