In industrial sensing,precision measurement and other scenes,high-performance analog-to-digital converter is the core component to ensure the accuracy of signal acquisition.ADX122AQFN10,as a 20-bit high-precision ADC analog-to-digital converter,is perfectly compatible with the AD7781 chip.With its core advantages such as ultra-low power consumption,high integration and strong anti-interference,it has become the preferred alternative for small and medium-sized precision measurement and control systems,effectively reducing the cost of equipment development and hardware replacement.
 

This precision ADC analog-to-digital converter adopts mature SD architecture design,and is equipped with QFN-10 ultra-small package,with a size of only 2mm×1.5mm×0.4mm At the same time,MSOP-10 package is optional,which is suitable for all kinds of equipment scenes with limited space.The ADC analog-to-digital converter chip is highly integrated,with low drift voltage reference,built-in oscillator,programmable gain amplifier(PGA),intelligent anti-power frequency interference filter and digital comparator,which greatly simplifies the system structure and improves the stability of the equipment.
 

In signal acquisition,the analog-to-digital converter ADX122AQFN10 is equipped with multiple input channels,which supports two-way differential and four-way single-ended signal acquisition and is suitable for multi-type sensor signal detection.Programmable gain amplifier can cover a wide input range from±256mV to 6.144 v,and can realize high-precision sampling for both weak small signals and large analog signals.The output data rate of ADC analog-to-digital converter chip is flexible and adjustable,ranging from 10SPS to 3571SPS,which meets the measurement requirements of different accuracy and speed.
 

ADC analog-to-digital converter supports 2V-5.5V wide voltage supply,and is equipped with standard SPI communication interface to adapt to mainstream main control equipment.The working temperature ranges from-40℃to 125℃,and its performance is stable in high and low temperature environments.With its small size,low power consumption and high precision,it is widely suitable for industrial sensing detection,portable precision equipment,low power consumption measurement and control terminals and other scenarios,and it is a cost-effective and compatible alternative model of the AD7781 chip.
