">The ADS1118 is a precision analog-to-digital converter (ADC) with 16 bits of resolution. The ADS1118 is designed with precision, power, and ease of implementation in mind. The ADS1118 features an onboard reference and oscillator. Data are transferred via a serial peripheral interface (SPI). The ADS1118 operates from a single power supply ranging from 2V to 5.5V.

The ADS1118 can perform conversions at rates up to 860 samples per second (SPS). An onboard programmable gain amplifier (PGA) is available on the ADS1118 that offers input ranges from the supply to as low as ±256mV. This range allows both large and small signals to be measured with high resolution. The ADS1118 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. The ADS1118 can also function as a high-accuracy temperature sensor. This temperature sensor can be used for system-level temperature monitoring or cold junction compensation or thermocouples.

The ADS1118 operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces current consumption during idle periods.
