Analog-to-digital Converter ADS1115 (ADS1015)

The distinctive characteristics of this ADC is its low power consumption of only 150 µa in operational mode, built-in programmable input amplifier, built-in voltage reference. In total, the chip has 4 inputs (A0 - A3) that can be used as two differential inputs to measure the voltage difference between the inputs, or as 4 separate single-ended inputs; in this case the voltage is measured between one of the inputs and ground. The necessary combination of inputs can be set using the built-in multiplexer.

VERY IMPORTANT!!!: This module is very afraid of over-voltage as inputs, and nutrition. The excess voltage of more than 5% of the supply voltage it will instantly burn.

System address setting I2C ADS1115

This unit involves the installation address for I2C bus using the ADDR output circuit in the digital signal insights or conclusions power bus. Set different I2C addresses intended for, so if you connect two or more different devices there were no conflict between them, because in the best case, the modules whose addresses match simply will not work, and at worst the work of all modules on the bus can be unpredictable. Looks like the address selection is shown in the figure below.
