Class D digital power amp (PurePath Digital/spl trade/) high Q musical content

The complex aspects of digital class D audio amplification and related technology issues are discussed. The focus is on a 100 W into 4 /spl Omega/ bridge-tied-load (BTL) power stage PIC. A 0.35 /spl mu/m BCD technology (LBC5) having 50 V LDMOS, and 10 /spl mu/m plated CuNiPd power metal, with bonding capability, was used to fabricate the chip.
