使用 Analog Devices 的 AD7793BRUZ 的参考设计

supremeOne 发布

EVAL-CN0326-PMDZ 评估板是一款完全隔离的低功耗 pH 传感器信号调节器和数字转换器，具有自动温度补偿功能，可实现高精度。该电路可为 0 至 14 的 pH 值提供 0.5% 的准确读数，具有超过 14 位的无噪声代码分辨率，适用于化学、食品加工、水和废水分析等各种工业应用。该电路支持各种 pH 传感器，这些传感器具有非常高的内阻，范围从 1 M 欧姆到几 G 欧姆，数字信号和电源隔离可防止恶劣工业环境中经常遇到的噪声和瞬态电压

说明

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
