If you need a higher resolution or your project requires analog readings, the ADS1115 can support up to 16-bit precision at 860 samples per second over I2C. You can configure the chip to be 4 inputs or 2 differential channels. It also packs a programmable gain amplifier of up to 16x.
Device address can be changed to one of the four options so technically you can connect up to 4 of these ADC together to give you a 16 channel 16-bit ADC.
