16-bit, 860-SPS four-channel delta-sigma ADC with PGA, comparator and 1.8-V I²C bus voltage support

The ADS1114L and ADS1115L (ADS111xL) are precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in ultra-small, 12-pin DSBGA and a 10-pin VSSOP packages. The ADS111xL incorporate a low-drift voltage reference and an oscillator. The ADS111xL also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with the device wide operating supply range, are useful for power- and space-constrained, sensor measurement applications.

The ADS111xL perform conversions at data rates up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1115L features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS111xL for under- and overvoltage detection.
