General description
The TFA9881 is a mono, filter-free class-D audio amplifier in a 9-bump WLCSP (Wafer Level Chip-Size Package) with a 400 m pitch.
The digital input interface is an over-sampled Pulse Density Modulated (PDM) bit stream.
The TFA9881 receives audio and control settings via this interface.
Dedicated silence patterns are used to configure the control settings of the device, such as mute, gain, Pulse Width Modulated (PWM) output slope, clip control and bandwidth extension (this control mechanism is not required if the default settings are used).
The Power-down to Operating mode transi...
