Other Parts Discussed in Thread: ADS1235
Hello Experts,
My customer has question as follows.
[Question 1]
I decided to check the settings from the console.
Offset calibration was done with SYOCAL command, but with GANCAL command, SYGCAL command was selected with gain 1V/V register setting, but it changed from 5mV to 200mV.There was a formula in 8.4.7.6, but I do not understand this relationship well, could you tell me about the relationship and the operation?
The image of what you want to do is as follows.
Code: -53 => Code: 0 (sensor input voltage 0 mV) SYOCAL command?
Code:8250 => Code:5000 (sensor input voltage 5mV)
Code:16552 => Code:10000 (sensor input voltage 10mV)
[Question 2]
I would like to measure the filter using data rates 2.5, 5, 10, 100 sps.
Looking at the noise table in Table 1 of the ADS1235 data sheet, the Sinc4 filter suppresses the noise the most.
The FIR filter is set by default, but is there a disadvantage with the Sinc4 filter?
Best Regards,
Fujiwara
