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).

Small outline WLCSP9 package: 1.27 × 1.49 × 0.6 mm Wide supply voltage range (fully operational from 2.5 V to 5.5 V) High efficiency (90 %, 4 Ω/20 μH load) and low power dissipation Quiescent power: 6.5 mW (VDDD = 1.8 V, VDDP = 3.6 V, 4 Ω/20 μH load, fs = 32 kHz) 7.65 mW (VDDD = 1.8 V, VDDP = 3.6 V, 4 Ω/20 μH load, fs = 48 kHz) Output power: 1.4 W into 4 Ω at 3.6 V supply (THD = 1 %) 2.7 W into 4 Ω at 5.0 V supply (THD = 1 %) 3.4 W into 4 Ω at 5.
