ADX111AMSOP10

The ADX111(Q) is a precision, low-power, 16-bit resolution, I2C-compatible ADC available in MSOP-10 and QFN-10 packages. The high level of integration helps reduce system design complexity and cost. The device integrates a low-drift voltage reference, oscillator, PGA, and digital comparator. An internal digital filter provides flexible output data rates from 8 SPS to 860 SPS. The PGA supports input ranges from ±256 mV to ±6.144 V, enabling accurate measurement of both large and small signals. A single input MUX supports two differential or four single-ended input measurements. A digital comparator is provided for undervoltage and overvoltage detection. The ADX111(Q) operates in either continuous-conversion mode or single-shot mode. The internal filter is single-cycle settled in both modes. In single-shot mode, the device automatically powers down after completing one conversion, significantly reducing power consumption during idle periods. The ADX111(Q) operates over a wide supply voltage range, making it well suited for power- and space-constrained sensor measurement applications.
