The ADS1018-Q1 is a precision, low power, 12-bit, noise-free, analog-to-digital converter (ADC) that provides all features necessary to measure the most common sensor signals. The ADS1018-Q1 integrates a programmable gain amplifier (PGA), voltage reference, oscillator, and high-accuracy temperature sensor. These features, along with a wide power-supply range from 2 V to 5.5 V, make the
ADS1018-Q1 ideally suited for power- and space-constrained, sensor-measurement applications.

The ADS1018-Q1 performs conversions at data rates up to 3300 samples per second (SPS). The PGA offers 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) 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.

The ADS1018-Q1 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. Data are transferred through a serial peripheral interface (SPI™). The ADS1018-Q1 is specified from –40°C to +125°C.
