ADX111QAMSOP10 analog-to-digital converter(ADC)

The ADX111QAMSOP10 device is precision,low-power,16-bit,I2C-compatible,analog-to-digital converter(ADC)offered with MSOP-10 and QFN-10 packages.

The ADX111QAMSOP10 device incorporates a low-drift voltage reference and an oscillator.It also incorporates a programmable gain amplifier(PGA)and a digital comparator.These features,along with a wide operating supply range,make the ADX111QAMSOP10 well suited for power-and space-constrained,sensor measurement applications.

The ADX111QAMSOP10 performs conversions at data rates up to 860 samples per second(SPS).Internal digitalfilter provides flexible output data rate,from 8SPS to 860SPS.The PGA offers input ranges from±256mV to±6.144V,allowing precise large-and small-signal measurements.

The ADX111QAMSOP10 features an input multiplexer(MUX)that allows two differential or four single-ended input measurements.Use the digital comparator in the ADX111QAMSOP10 for under-and overvoltage detection.

The ADX111QAMSOP10 operates in either continuous￾conversion mode or single-shot mode.The internal filter is single-cycle settling in both modes.The devices are automatically powered down after one conversion in single-shot mode;therefore,power consumption is significantly reduced during idle periods.See Table 1 for the order information.
