Description
Texas Instruments ADS1115 — 16-bit delta-sigma ADC with four single-ended or two differential inputs, integrated programmable-gain amplifier (×2/3 to ×16), internal voltage reference, and an I²C interface. Up to 860 samples/s. Wide 2.0–5.5 V supply makes it 5 V-tolerant on logic when run from a 5 V rail. Default I²C address set by the ADDR pin (one of 0x48/0x49/0x4A/0x4B).
