Hi,
we like to measurement a DC signal and use the TLV320ADC3120 in the DC-coupled input (CH1_CFG0 Register). We don't have a capacitor in the signal line.
We have a 10% DC offset in the measuring Range.
The configuration:
- Line Input with a differential Amplifier stage.
- LJ (TX_Offset = 0);
- 2 Channel with 2.82Vpp input common-mode
- AVDD 3.3V
- No channel gain
I hope you can help me.
Thanks, Anastasios
