For Analog Audio Processors, For products with VOL and FADER, how can I use them to reduce output noise?
To reduce the output noise level, decrease the gain of the FADER in the second stage instead of the VOL in the first stage.
For Analog Audio Processors, What are the benefits of using ground-isolated inputs?
The ground isolation input is effective in removing Common Mode Noise superimposed on both the signal input and GND. For example, it is effective when the same noise is on the GND side and the signal side, such as when a signal from an external device is input via RCA cables.
For Analog Audio Processors, Do I also need to set the registers to its initial values?
When power is turned on, be sure to send data to all addresses as initial data. It is also recommended to mute the device until the initial data is transmitted.
For Analog Audio Processors, How should unused output pins be handled?
Unused output pins can be left OPEN.
For Analog Audio Processors, What type of product is Hi-VOL type?
Typical output of analog audio processors is about 2Vrms. Hi-VOL type can output 3 to 5Vrms.
你好，我们有用到ADI品牌的 LT8301ES5和ROHM的BD4840FVE-TR的IC,我们现在想找国产IC可以替代的，性能一致就可以，是否有推荐的国产品牌可以替代呢？
推荐圣邦微隔离电源芯片SGM46000（替代LT8301ES5）和复位芯片SGM706-J（替代BD4840FVE-TR），均为功能性替代，相关技术资料参考链接：SGMicro（圣邦微） SGM46000 3W主变压器和用于隔离电源H桥驱动器数据手册SGMicro（圣邦微）SGM706 Low-Cost, Microprocessor Supervisory Circuit
12V输入，给3节锂电池（12.6V）充电的充电管理芯片有吗？电流2A即可。
推荐ROHM品牌的锂电池充电管理芯片：BD99954MWV，支持最多4节锂电池串联充电方式，产品带通讯接口。详细参数看如下链接 1 to 4-Cell Li-Ion Battery Manager For Application Processors BD99954MWV, BD99954GW数据手册
For Analog Audio Processors, How should unused input signal pins be handled in a product that operates with One or Two Positive Power Supplies?
Since the voltage at the input terminal is a Bias Voltage, it is recommended to connect it to GND via a Coupling Capacitor. It is also possible to leave OPEN the unused input signal pins, but External Noise, Crosstalk, etc. are more likely to occur.
有没有IIC接口的单节锂电池充电管理芯片。多介绍几种，还在选型。

For BD37033FV-M,BD37034FV-M,BD37524FS,BD37534FV,BD37543FS, What is the level meter function?
The Level Meter is a circuit that outputs a DC voltage proportional to the magnitude of the signal and holds the peak level of the detected signal. Since the held peak level can be reset by resetting the Level Meter, the transition of the peak level can be monitored by periodically performing a reset. The reset interval should be at least one cycle of the frequency to be monitored.
For Analog Audio Processors, For a product that operates with One or Two Positive Power Supplies, is accurate capacitance value required for the Coupling Capacitor of unused input signal terminals?
Accurate capacitance value is not required, but since the HPF is formed by the Coupling Capacitor and the internal input Resistor, the noise frequency bandwidth that can be filtered varies depending on the capacitance value to be connected.
When performing A/D conversion for multiple channels, are channels put into the sampling wait state until sampling of one channel is completed? Or, can sampling be performed simultaneously?
The ADC of our microcontroller performs A/D conversion while switching channels and therefore unprocessed channels are put into the wait state. Simultaneous conversion cannot be performed.
What happens if there are less through holes on GND for the back side GND pad of the chip?
GND may be shaken and various RF characteristics would be worse. Even if 12 through holes are used, the same situation would happen unless connected GND plane is strengthed. Related Products: ML7344/ML7406 family, ML7345 family, ML7396 family, ML7404, ML7414
For Analog Audio Processors, Can a product that writes commands via I2C I/F also read back register values?
Reading of register value is not supported.
Is it possible to use direct conversion (zero IF)?
Setting is possible. However, the sensitivity is affected because the leakage of local frequency components to the ANT always appears as Co-Channel interference. For this reason, its use is not recommended. Related Products: ML7345/ML7345D, ML7404, ML7414
