ADS1118 16-bit ADC Breakout Board

Now available from PMD Way is the interesting and useful ADS1118 analog to digital converter on a convenient breakout board.

This is a breakout board in the true sense, the PCB breaks out all the pins of the ADS1118 and simply offers a smoothing capacitor over the power rails. Inline header pins are included but not soldered to the board. 

The ADS1118 is a precision, low power, 16-bit analog-to-digital converter (ADC) that provides all features necessary to measure 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 power supply 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 up to 860 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 to 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 current consumption during idle periods. Data are transferred through a serial peripheral interface (SPI™). The ADS1118 is specified from –40°C to +125°C.
