Fig.14 Two-chip class-D audio amplifier application diagram for TDA8926TH or TDA8927TH and TDA8929T. R9 and R10 are only necessary in BTL applications with asymmetrical supply. BTL: remove R6, R7, C4, C7 and C8 and close J5 and J6. Demodulation coils L2 and L4 should be matched in BTL. Inputs floating or inputs referenced to QGND (close J1 and J4) or referenced to VSS (close J2 and J3). |
