ADX111(including vehicle specification ADX111Q)is a precision analog-to-digital conversion chip with 16-bit high resolution,which is packaged in compact MSOP-10 and QFN-10 packages.Its core advantage lies in its high integration:it integrates key modules such as low drift voltage reference,oscillator,programmable gain amplifier(PGA)and digital comparator.This highly integrated design significantly simplifies the peripheral circuits,not only reduces the complexity of system design,but also effectively controls the overall material and manufacturing costs.
High-speed analog-to-digital converter ADC supports programmable output data rate from 8SPS to 860SPS,and realizes flexible balance between speed and noise suppression through internal digital filter.Its PGA provides a wide input range from±256mV to 6.144 V,which enables it to accurately measure weak signals and handle input with large amplitude,so as to meet diverse measurement requirements.ADX111 high-speed analog-to-digital converter ADC is equipped with an input multiplexer,which supports four single-ended or two differential input configurations,which improves the convenience of multi-channel acquisition.
