The DADS1118 is an I2C-compliant 16-bit high-precision, low-power analog-to-digital converter (ADC) in an MSOP-10 package. It features a low-drift voltage reference and oscillator. The DADS1118 also incorporates a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply voltage range, make the DADS1118 ideal for power- and space-constrained sensor measurement applications. The DADS1118 can perform conversions at data rates up to 860 samples per second (SPS). 

The PGA provides an input range from ±256mV to ±6.144V, enabling accurate measurements of both large and small signals. The DADS1118 features a single input multiplexer (MUX) for two differential input measurements or four single-ended input measurements. Undervoltage and overvoltage detection can be performed using digital comparators within the DADS1118. The DADS1118 can operate in both continuous conversion and single- shot modes. In single -use mode, these devices can automatically power off after a single conversion; thus significantly reducing power consumption during idle periods.
