The devices are automatically powered down after one conversion in single-shot mode therefore, power consumption is significantly reduced during idle periods. The ADS1115 operates in either continuous-conversion mode or single-shot mode. Use the digital comparator in the ADS1115 for under- and overvoltage detection. The combination of an I2C serial, 2-wire interface and micropower consumption makes the I2C-ADC ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS1115 features an input multiplexer that allows two differential or four single-ended input measurements. The Analog-to-Digital (A/D) converter features a sample-and-hold amplifier and internal, asynchronous clock. The PGA offers input ranges from ☒56 mV to ☖.144 V, allowing precise large- and small-signal measurements. The ADS1115 perform conversions at data rates up to 860 samples per second (SPS). These features, along with a wide operating supply range, make the ADS1115 well suited for power- and space-constrained, sensor measurement applications. The ADS1115 also incorporate a programmable gain amplifier and a digital comparator. The ADS1115 device incorporates a low-drift voltage reference and an oscillator. The ADS1115 device is a precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package.
