问题可能出现在输入端的R4, 提高了输入的共模电压，您可以参见手册的Figure 9-2.Input Common-Mode Voltage vs Output Voltage at G = 1 V/V了解输入共模电压与输出电压范围的关系，也可以通过 input and output range design calculator 工具得出具体的输入电压范围。

Hello，
Could you get right value for fixed input signal?
Can it work correctly in "8.4.3.1 Continuous-Conversion Mode"?

Part Number: ADC12DJ5200RF According to the datasheet of ADC12DJ5200RF, it has three Functional Modes:
In my opinion, DES Mode means:
But how does the DUAL DES Mode work?The datasheet says "Dual-input single-channel mode is equivalent to dual channel mode…
您好
以前有人问过同样问题，下面是官方的回答：
CAL0/CAL1 are regular ADC inputs mapped to channel select for all ADCs. This can give you the flexibility to use these two channels on whichever ADCs you want. Alternatively, you could feed the same signal to multiple ADCs to calibrate…
您好，
BQ25672的I2C地址固定为0x6B, 无法更改。具体请参考数据手册"8.3.4"部分内容。

你试一下下面的测试条件。
The PSRR (Power Supply Rejection Ratio) measures the noise that propagates to the ADC by varying the power signal to inject noise:
Low frequency (1 kHz) and high frequency (1 MHz) noise signal with 200 mV is applied to the power rail
The…
