Other Parts Discussed in Thread: ADS130E08

Hello,

We have one question in TI ADS130E08.

->Lets consider below scenario.

We have set continuous analog to digital conversion mode and conversion is ongoing at 8ksps rate.

->What if we meanwhile write particular channel's CHnSET register with new PGA gain value?

->After how much delay will the conversion take place with new gain value?

->or will 'new gain value' not come into effect until new conversion starts after power down/reset?

Thanks.

Hello Divyesh -
The gain setting will take effect on the 8th SCLK of the write command. You will need to wait for the data to settle before the data reflects your change (similar to datarate change or other).
