TFA9896UK数据手册恩XP中文资料规格书

描述 Description

The TFA9896 is a high-efficiency class-D audio amplifier with a sophisticatedSpeakerBoost protection algorithm. It can deliver 2.1 W (RMS; THD = 1 %) output powerinto an 8 Ohm speaker at a battery voltage of 3.6 V. The internal boost converter raisesthe supply voltage to 6.1 V, providing ample headroom for major improvements in soundquality.

特性 Features
