TFA9874, embedded with DSP is a highly power-efficient class-D audio amplifier
solution associated with speaker protection and boost algorithm.
- 5.6W into 8 Ω, 6.2W into 4 Ω (THD<1%; VBAT= 4V)
- Very low noise:<14μV
10V Adaptive DC-DC Boost
- Maximizes the output power of the Class-D audio amplifier while preventing large battery supply spikes and limiting quiescent power consumption
