Hi

I have couple of questions:

1. To Calculate output voltage you use Equation 10:

Which you take FSR from Table 8-1 (Is FSR = 75mV for gain 16 or is 150mV becuase +-)

Ex: in below equation for Gain 16 the LSB = 0.075/2^23 = 8.9407E-09

2. Calculate offset:

- Connect both AINXP and AINXN to AGND and measure offset and insert it to CHX_OCAL_LSB and CHX_XCAL_MSB:

- Ex: the offset is 8uV how do you convert this to bin with two complements Do you divide this by LSB

8uv/8.9407E-09 = 894.7848533 which will take int 894 and convert it to hex 0x37E, then I write 3 on MSB and 7E on LSB

3 - Gain calibration:

- I use equation 13

- How do I convert the Gain to bin.

Ex: 0.98 is gain Error how do I find actual bin in two's complement. (Will be same as Offset calculation)

Please let me know if you have any questions.
