I have some questions about TIDA-00854 Micropower Electrochemical Gas Sensor Amplifier Reference Design
In the schematic design document of TIDA-00854, the resistance RC is placed between the CE pin of the gas sensor and the op amp output, while in the TIDA-00854 design guide, the resistance RC is placed between the RE pin of the sensor and the negative input of the operational amplifier. Why is the resistance RC designed between the CE pin of the gas sensor and the op amp output in the schematic design document?
Thanks
