Description
ADS1118 module is an analog to digital converter module that has 16-bit precision and can measure a maximum voltage of 7 volts. This module measures the potential difference between two input pins.
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.
