ADS1015 - 12-Bit, 3.3kSPS, 4-Ch Delta-Sigma ADC With PGA, Oscillator, VREF, Comparator and I2C Interface

The ADS1013, ADS1014,and ADS1015 devices (ADS101x) are precision,low-power, 12-bit, I²C-compatible, analog-to-digital converters (ADCs)offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10package. The ADS101x devices incorporate a low-drift voltage reference and anoscillator. The ADS1014 and ADS1015 also incorporate a programmable gain amplifier (PGA) and a digitalcomparator. These features, along with a wide operating supply range, make theADS101x well suited for power- and space-constrained, sensor measurementapplications.

The ADS101x perform conversions at data rates up to 3300 samples persecond (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- andsmall-signal measurements. The ADS1015 features an inputmultiplexer (MUX) that allows two differential or four single-ended input measurements. Use thedigital comparator in the ADS1014 and ADS1015 for under- and overvoltage detection.

The ADS101x operate in either continuous-conversion mode orsingle-shot mode. The devices are automatically powered down after one conversion in single-shotmode; therefore, power consumption is significantly reduced during idle periods.
