Other Parts Discussed in Thread: ADS1120, ADS1220, ADS114S06
Hi Sirs,
Please help on these questions.
Thanks.
1. While using single-end input, the int. PGA needs to disable or not? And if disabled the PGA, what the input impedance will be?
2. For ratiometric measurement, is it ok to use the below connection?
3. If the connection of Q2 is OK, are there any solutions else with the same performance but lower cost from ADS124S06/08?
