Product Overview

The EVAL-CN0326-PMDZ circuit evaluation board is a completely isolated low power pH sensor signal conditioner and digitizer with automatic temperature compensation for high accuracy. It uses AD7793 three channel low noise and low power 24bit sigma delta ADC, ADuM5401 quad channel Isolators with Integrated DC to DC converter and AD8603 MicroPower RRIO low noise precision single CMOS opamp. The circuit gives 0.5% accurate readings for pH values from 0 to 14 with greater than 14bits of noise free code resolution and is suitable for a variety of industrial applications such as chemical, food processing, water and waste water analysis. This circuit supports a wide variety of pH sensors that have very high internal resistance that can range from 1Mohm to several Gohm and digital signal and power isolation provides immunity to noise and transient voltages often encountered in harsh industrial environments.
