• EVAL-CN0326-PMDZ, Evaluation Board is a completely isolated low power pH sensor signal conditioner and digitizer with automatic temperature compensation for high accuracy. The circuit gives 0.5% accurate readings for pH values from 0 to 14 with greater than 14-bits of noise-free code resolution and is suitable for a variety of industrial applications such as chemical, food processing, water and wastewater analysis. This circuit supports a wide variety of pH sensors that have very high internal resistance that can range from 1 M-Ohm to several G-Ohm, and digital signal and power isolation provides immunity to noise and transient voltages often encountered in harsh industrial environments
