How about my ADS1220 circuit? [Copy link]

This is the first time I use a 24-bit AD ADS1220. I refer to the circuit on the Internet and the schematic diagram is as follows. Can you guys see if there are any problems? Thank you!

The circuit diagram you provided has some problems. This is the final one. +IN1, -IN1 connect to the sensor signal line, excitation voltage 10.4V, output sensitivity 2mV/V. What I mean is, 2mV/V, 10.4V corresponds to 20.8mV, ADS1220 maximum gain 128, that is 20.8*128=2.66V. Can you take a look, is there any mistake? Thank you!

This is only part of the circuit diagram, and the VCC is the power supply
