Part Number: ADS1299 Initially, when using other solutions for EEG signal acquisition, we encountered a severe interference problem during EMC immunity tests (EFT, surge) of EEG acquisition. Because IEC 60601-2-26:2012 requires in section 202.6.2.4.1 that…

Hello,According to the suggestion:"datasheet 19 page “The VSET voltage is applied using a DAC through a 20kΩ series resistor."
As shown below
test circuit :
Correction…
您是否使用ADS1248电流源(IDAC)生成1mA电流? 如果是,则使用IDAC = 1mA时,REF = 10Kohm是过高的
此外,您测量的是什么电路? 2线,3线或4线RTD? 如果您正在测量3线RTD,您正在使用多少个IDAC (1x或2x)?
公式正确。 2的"额外"因子是因为ADC代码范围是双极的,并且从-FS扩展到+FS。 所以满刻度范围(FSR)=+FS --FS = 2*FS
Are you using the ADS1248 current sources…
