Hi,
There are some questions about LTC2141-14 that I want to ask.
1.As below,how to define these items:full-scale drift,gain matching,offset matching?

2.When using single end input,why does INL degrade,but the noise and DNL will remain unchanged. What factors will cause INL and DNL changed?

3.As you konw,LTC2141-14 is powered by 1.8V,but the input range can be 2Vpp, how to achieve this?
Thanks!
For 2V input range, the inputs should swing from VCM – 0.5V to VCM + 0.5V. There should be 180° phase difference between the inputs. Since this is a differential voltage measurement there is 1V difference between the signals at one extreme, and -1V at the other extreme. Combine (1 minus -1=2Vpp) is 2Vpp of input range.
