ADS1118 16-bit Analog-to-Digital ADC Converter Module SPI Interface

Description
The ADS1118 is a precision, low power, 16-bit analog-to-digital converter (ADC) that provides all the features needed to handle the most common sensor signals in an ultra-small, leadless X2QFN-10 package or a VSSOP-10 package. The ADS1118 integrates a programmable gain amplifier (PGA), voltage reference, oscillator and high accuracy temperature sensor. These features, along with a wide voltage range from 2 V to 5.5 V, make the ADS1118 ideally suited for power and space-constrained sensor-measurement applications.
The ADS1118 can perform conversions at data rates of up to 860 samples per second (SPS). The PGA provides input ranges from ± 256 mV to ± 6.144 V, allowing both large and small signals to be measured with high resolution. An input multiplexer (MUX) can be used Measure two differential or four single-ended inputs. The high accuracy temperature sensor can be used for system-level temperature monitoring or cold-junction compensation for thermocouples.
The ADS1118 operates either in continuous conversion mode, or in a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces power consumption during idle periods. Data is transferred through a serial peripheral interface (SPI ™). The ADS1118 is specified from -40 ° C to + 125 ° C.
