Part Number: BQ79731-Q1
请教2个关于BQ79731的问题：
1）BQ79731的规格书介绍内部ADC的特性及参数描述内容不多，是否能提供其他相关的应用资料呢？
2）正常情况电池PACK+/-的采样电压只有2-3V，但是PACK+/-后端接的是电机负载，由于电机在低速工作的时候EMI比较严重，对PACK+/-上产生了多种混合频率的电流纹波（频率跨度范围大，50kHz以上）
我们是不是可以认为会产生如下几个不利因素?
①多种频率的白噪声及分配噪声混合叠加到采样电路的电压分量上
②有很大的机率一定会导致ADC内部的放大器振荡
③虽然采样电压只有2-3V，但是极端情况会导致运放输出端出现顶格(5V)或者极性反转（0V）？
此外，想听听你们对于这种情况的看法，并纠正我的错误，谢谢
Please ask two questions about BQ79731:
1) The specification of BQ79731 does not introduce the characteristics and parameter description of the internal ADC, can you provide other relevant application information?
2) Under normal circumstances, the sampling voltage of battery PACK+/- is only 2-3V, but PACK+/- is connected to the motor load at the back end. Due to the serious EMI of the motor at low speed, a variety of mixed frequency current ripple (large frequency span, more than 50kHz) is generated on PACK+/-.
Can we think that there will be the following unfavorable factors?
① White noise and distribution noise of multiple frequencies are mixed and superimposed on the voltage component of the sampling circuit
There is a high probability that the amplifier inside the ADC will oscillate
Although the sampling voltage is only 2-3V, extreme cases will lead to a top grid (5V) or polarity reversal (0V) at the output end of the op amp.
In addition, I would like to hear your opinions on this situation,And correct my mistakes, thank you！
