TFA9882 3.4 W I2S input mono class-D audio amplifier

The TFA9882 is a mono, filter-free class-D audio amplifier in a 9-bump WLCSP (Wafer Level Chip-Size Package) with a 400 μm pitch. It receives audio and control settings via an I2S digital interface. The Power-down to Operating mode transition is triggered when a clock signal is detected on the bit c.
