Overview

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

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

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)

Single Power Supply

5 V USB Type-C

Low-Dropout
Regulation

DC-to-DC and LDO

Temperature Control

Interface temperature monitor

External

32 MB HyperFlash

Internal

1 MB on-chip SRAM
