TFA9882UK: 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 clock input (BCK). Two devices can be combined to build a stereo application.
In stereo applications, the left or right I²S audio stream is selected by connecting the word select signal to, respectively, pin WSL or pin WSR. Mono mixing can be achieved by connecting the word select signal to both WSL and WSR. Switching off the word select signal selects Mute mode.
The device features low RF susceptibility because it has a digital input interface that is insensitive to clock jitter. The second order closed loop architecture used in the TFA9882 provides excellent audio performance and high supply voltage ripple rejection.
