The TFA9894D is a highly power-efficient class-D audio amplifier solution with speaker protection and boost algorithm

5.6 W into 8 Ohms, 6.2 W into 4 Ohms (THD <1%; VBAT= 4 V), Very low noise: <14 μV

Adaptive DC-DC Boost
10 V – Maximizes the output power of the class-D audio amplifier while preventing large battery supply spikes and limiting quiescent power consumption

Power Optimization
High system efficiency: 91% peak efficiency for 600 mW sine wave, low battery consumption: <125 mA (Po = 380 mW, average music power)
