3.4 W PDM input class-D audio amplifier

Overview \nThe TFA9881 is a mono, filter-free class-D audio amplifier in a 9-bump WLCSP (Wafer Level Chip-Size Package) with a 400 μm pitch.\n\nThe digital input interface is an over-sampled Pulse Density Modulated (PDM) bit stream. The TFA9881 receives audio and control settings via this interface. \n\nSmall outline WLCSP9 package: 1.3 × 1.3 × 0.6 mm\n\nWide supply voltage range (fully operational from 2.5 V to 5.5 V)\n\nHigh efficiency (90 %, 4 Ω/20 μH load) and low power dissipation\n\nQuiescent power:\n6.5 mW (VDDD = 1.8 V, VDDP = 3.6 V, 4 Ω/20 μH load, fclk = 2.048 MHz)\n\n7.8 mW (VDDD;
