I need help regarding the Analog input protection of ADS1115 This circuit reads industrial sensors ranging from 0-10V and 4-20mA to a 0-3.3V output. ...
I am avoiding the ESP32 S3 ADC due to its lower reliability. Instead, I am switching to the ADS115. According to the datasheet for ADS115, the maximum analog input voltage is VDD + 0.3V. Since I will provide a VDD of 3.3V, this means the maximum input voltage is 3.3V + 0.3V = 3.6V. The circuit I created produces voltages ranging from 3.488V to 3.56V. see below ... The datasheet states that if your input violates the maximum rating mentioned above, you should use the Schottky diode circuit that I created. Will my circuit work, or should I consider any other requirements? ...
