Low noise 24-bit high precision ADC analog-to-digital converter

 

　　ADC analog-to-digital converter is the core component to realize the conversion of data signals from analog world to digital world.The analog products represented by Yingshang provide a series of ADC chips with excellent performance,which have won unanimous recognition for their outstanding control accuracy and stability.Among them,ADX517 model is an excellent 24-bit high-precision ADC analog-to-digital converter.Because of its outstanding noise control and stability,it provides strong support for many high-precision measurement scenarios.

 

 

　　ADX517,as a low-noise 24-bit high-precision ADC analog-to-digital converter,is designed with full consideration of information system integration and signal integrity.Multiplexer,high-frequency signal input buffer and programmable gain control amplifier are integrated in the chip,among which PGA supports gain control adjustment of 1 to 128 times,which can flexibly adapt to different amplitude input signals and further improve the dynamic range and measurement sensitivity of the system.

 

　　The ADC analog-to-digital converter is equipped with a programmable digital filter,which can not only achieve noise-free resolution of up to 23 bits,but also support the conversion rate of up to 60kSPS.The filter circuit supports single-cycle stable conversion,and can be specially equipped to suppress 50Hz and 60Hz power frequency interference,which greatly improves the anti-interference in complex electromagnetic environment.The communication interface adopts SPI-compatible design,which can run with only three wires,greatly simplifying the connection and wiring with the main control chip.
