ADS1018IRUGT .

The ADS1018IRUGT is a 12-bit Analog-to-digital Converter (ADC) that provides all features necessary to measure the most common sensor signals. The precision low-power noise-free ADC integrates a programmable gain amplifier (PGA), voltage reference, oscillator and high-accuracy temperature sensor. This features along with a wide power-supply range from 2 to 5.5V. It performs conversions at data rates up to 3300SPS. The PGA offers input ranges from ±256mV to ±6.144V allowing both large and small signals to be measured with high resolution. An input multiplexer allows measurement of two differential or four single-ended inputs. The high-accuracy temperature sensor is used for system-level temperature monitoring or cold-junction compensation for thermocouples. It operates either in continuous-conversion mode or in a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces current consumption during idle periods.
