BD37069FV-M中文资料内置2次后置滤波器/High-Voltage功能 车载音响用声音处理器数据手册ROHM规格书

描述 Description

BD37069FV-M内置6ch立体声输入选择器，调节信号电平并输出至AD转换器。分别内置6ch的2次后置滤波器与音量控制器，用于降低从DA转换器输出的信号的带外噪声，可将最大输出放大至5.2VRMS。还搭载了TDMA降噪功能，为整机设计的简化作出了贡献。

特性 Features

• AEC-Q100 Qualified
• Built-in differential input selector that can select single-ended / differential input
• Reduce switching pop noise of input gain control due to the built-in advanced switch circuit
• Less out-of-band noise of DAC by built-in 2nd order post filter
• Built-in buffered ground isolation amplifier to achieve high CMRR characteristics
• Built-in TDMA noise reduction circuit reduces the additional components for external filter
• Available to output 5.2VRMS by High-Voltage function (This device is possible to 3.2VRMS output by using another High-Voltage mode, VCCH=11.5V)
• Available to control by 3.3V / 5V for I2C-bus controller
• The input and output terminals are located together to arrange the flow of signal in a same direction making the PCB layout easier and PCB area smaller
