8.4.5 IV Sense

The TAS2563 provides speaker voltage and current sense for real time monitoring of loudspeaker behavior. The

VSNS_P and VSNS_N pins should be connected after any ferrite bead filter (or directly to the OUT_P and

OUT_N connections if no EMI filter is used). The V-Sense connections eliminate IR drop error due to packaging,

PCB interconnect or ferrite bead filter resistance. It should be noted that any interconnect resistance after the V-

Sense terminals will not be corrected for, so it is advised to connect the sense connections as close to the load

as possible.
