TDA7435D 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The audioprocessor TDA7435 is an upgrade of the TDA731X audioprocessor family.
Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained.
A second programmable high pass filtering provides the loudspeakers equalization.
