Dear Sir,
We are excited to see pH monitor with Temperature compensation application and would like to know more on this as below
1) This has reference to the configuration available in the evaluation kit Ref EVAL-CN0326-PMDZ Board
2) We understand from your Description for pH application following are important
....Guarding, shielding, high insulation resistance standoffs, and other such standard picoamp methods must be used to minimize leakage at the high impedance input of the AD8603 buffer...
3) But in the Evaluation Board we do not see any High Insulation resistance StandOff , nor any shield available?. We see in EVAL-CN0326-PMDZ Board, AD8603 IC pin 3 is directly soldered to PCB and pH probe input is connected to this point. We wish to know wheather PCB impedance is acceptable by doing so for this application?
4) We are unable to find uC firmware C source code for this pH application for this kit? Can we get the same?
5) What modification need to be done for pt 100 RTD?
Thanks
