Hi
Would you help review my customer's schematics below, are the schematics and the component value on the RLD path looks ok?
The application is 2CH ECG，CH1 : LA and RA and CH2 : LL and RA
Also using this circuit we see an issue that when applied dc-offset 300mV on RA or LA , the ADC reading value will be saturated, any suggestion how to solve it ?
Below is our register setting
ADS1x9x_Reg_Write(ADS1x9x_REG_CONFIG1, 0x80);
ADS1x9x_Reg_Write(ADS1x9x_REG_CONFIG2, 0xA0);
ADS1x9x_Reg_Write(ADS1x9x_REG_LOFF, 0x10);
ADS1x9x_Reg_Write(ADS1x9x_REG_CH1SET, 0x40);
ADS1x9x_Reg_Write(ADS1x9x_REG_CH2SET, 0x60);
ADS1x9x_Reg_Write(ADS1x9x_REG_RLD_SENS, 0x2C);
ADS1x9x_Reg_Write(ADS1x9x_REG_LOFF_SENS,0x00);
ADS1x9x_Reg_Write(ADS1x9x_REG_RESP1,0xF2);
ADS1x9x_Reg_Write(ADS1x9x_REG_RESP2,0x03);
