特性 Features

SPK Class-D
• 5.6 W into 8 Ohms, 6.2 W into 4 Ohms (THD <1%; VBAT= 4 V)
• Very low noise: <14 μV
10 V 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
Power consumption
• High system efficiency: 91% peak efficiency for 600 mW sine wave
• Low battery consumption: <125 mA (Po = 380 mW, average music power)
Embedded SpeakerBoost Algorithm
• Speaker damage protection for thermal mechanical damage overload and enhanced loudness on speaker
• On host or DSP integrated only on TFA9894 (V2.0)
MCU platform digital IO support
• 3.3 V Digital IO support

应用 Application

Consumer Electronics
