8.4.5 IV Sense

The TAS2562 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.

TAS2562 tas2564_vsns_connect.gifFigure 67. V-Sense Connections

I-Sense and V-Sense can be powered down by asserting the ISNS_PD and VSNS_PD register bits respectively. When powered down, the device will return null samples for the powered down block. The IV-sense is High Passed Filtered and the Bi-Quad filter coefficients can be changed from the default 2 Hz using the IVHPFC_N0, IVHPFC_N1, IVHPFC_D1 registers using the equations [N, D] = butter(1, fc/(fs/2), 'high'); round(N(0)*2^31);. These coefficients can be calculated and set using PurePath™ Console 3 Software.
