TDA8922CTH数据手册恩XP中文资料规格书

描述 Description

The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is 2 x 75 W with a speaker load impedance of 6 Ω.
The TDA8922C is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from +-12.5 V to +-32.5 V and features low quiescent current consumption.

特性 Features
