ADS1115 16-Bit ADC

Texas Instruments' ADS1115 is a precision analog-to-digital converter (ADC) with 16 bits of resolution offered in an ultra-small, leadless QFN-10 package or an MSOP-10 package. The ADS1115 is designed with precision, power, and ease of implementation in mind, and features an onboard reference and oscillator. Data is transferred via an I²C-compatible serial interface; four I²C slave addresses can be selected. The ADS1115 operates from a single power supply ranging from 2.0 V to 5.5 V.

The ADS1115 can perform conversions at rates up to 860 samples per second (SPS). An onboard PGA offers input ranges from the supply to as low as ±256 mV, allowing both large and small signals to be measured with high resolution.
