Notes

1. With open MUTE/ON pin, the TDA8591J will switch to operating mode (see Section 7.3)

2. VOO(det) is the offset voltage across the load. Pin OFFCAP should never be left open-circuit. If pin OFFCAP is

connected to one of the PGND pins, the offset detection is switched off (see Section 14.4).
