您好,有两个问题请教下:
1、NTC型号文件说用3450的换成3435影响大吗?
2、通讯输出的地,文件用的是P-做地,用电池B-做地是否有影响?(B-是芯片的GND)
谢谢!

您好
1,您看一下3435的热敏电阻系数是否和推荐的相同, 如果您切换热敏电阻,热敏电阻建模的默认多项式系数将无法在25摄氏度的温度下正常工作。
2, 建议用推荐的电路, The reasoning behind this is that the analog sensing that occurs via the SRN & SRP pins relative to the ground potential of the device is far more sensitive than the I2C communication.
