Hi there,
I have an arduino due connected to 4 ADS1115 modules to read 16 analog sensors. Three of ADS1115 with address(0x48, 0x49, 0x 4B) are working very well. However, ADS1115 with address pin connected to SDA to get 0x4A is responding with -1 on all channels. I tried to use different libraries but none of them works for me. I changed the board to Arduino Mega and the module works fine on that address. I also run I2C scanner with only the not working module connected and the scanner read (0x4B) while my address pin is connected to SDA. My final observation is that the module responds with correct data when I touch the address pin with my finger. and the address changes to 0x4A on i2c scanner. I hope someone guides me to the solution and thank you in advance. Note that all pads are soldered properly so the issue is not a bad contact.
