  • ADS1115: ADS1115: Best practice for unused analog input pins and ALERT/RDY pin

    Part Number: ADS1115 Hi Team, I am designing a circuit using the ADS1115 to sample two single-ended analog inputs. I plan to use AIN0 and AIN2 for my active signals, leaving AIN1 and AIN3 unused. Should the unused analog input pins be left floating…

  • ADS1115: Incorrect readings on ADS1115 connected to VDD and GND

    Part Number: ADS1115 Hi, I'm working with four ADS1115 ADCs connected to an ESP32 DevKit V1 using Arduino and I2C communication. I've configured the ADDR pins of each ADS1115 as follows to obtain I2C addresses according to the datasheet: ADDR to GND…

  • ADS1115: ADS1115: +/-5V Bipolar ADC with mV accuracy

    Part Number: ADS1115 Current design includes an ADS1115 but I am finding the non-linearity at upper end of the range to diviate too much. I am looking for an ADC that can handle an single sided input which ranges from -5 to 5VDC (or greater). I am not…
