The ADX114 is a precision, low-power, 16-bit resolution analog-to-digital converter (ADC) that is compatible with the I²C interface. Packaged in a QFN-10, the ADX114 integrates several functional modules, including a low-drift voltage reference, oscillator, programmable gain amplifier (PGA), power-line frequency rejection filter, and digital comparator, to simplify system design complexity and cost. The device features an input multiplexer (MUX) that supports two differential or four single-ended input measurements. The PGA provides an input range from ±256mV to ±6.144V, enabling precise measurement of both large and small signals. The internal digital filter of the ADX114 offers flexible output data rates ranging from 8 SPS to 860 SPS. The power-line frequency rejection filter can be configured for 50Hz or 60Hz rejection, or for simultaneous rejection of both 50Hz and 60Hz interference. The ADX114 operates in either continuous conversion mode or single-shot mode. The internal filter is single-cycle stable in both modes. In single-shot mode, the device automatically powers down after one conversion, significantly reducing power consumption during idle periods. ADC conversion results are transmitted via the SPI™ interface. Additionally, the ADX114 can operate over a wide supply voltage range, making it highly suitable for sensor measurement applications with power and space constraints.
