Analog devices, Inc. (NASDAQ: ADI) has launched a new generation of 16 to 24 bit ultra-high precision successive approximation register (SAR) analog-to-digital converter (ADC) products, which can simplify the complex ADC design in instrumentation, industrial and medical health applications. The new high-performance SAR ADC series adopts ADI's patented easy drive ™ Technology and universal Flexi SPI serial peripheral interface (SPI) solve the system design challenges and expand the selection range of directly compatible supporting products.
ADI's easy drive technology eliminates many traditional system level design challenges while maintaining device performance, such as strict layout guidelines and digital interface timing requirements, as well as complex supporting product selection. The universal Flexi SPI digital interface provides easy to meet timing requirements, thus simplifying host processor and ADC integration. The combination of high performance and this re conceived digital interface provides a better overall design experience, and also accelerates the system design cycle.
Among the six pin compatible SAR ADCs in this series, the first is the ad4630-24 with 24 bit dual channel synchronous sampling and 2 MSPs per channel. It has leading accuracy (inl) - rated at 0.9 ppm, which is four times higher than other solutions. The ad4630-24 integrates the reference buffer and all key decoupling elements into a single chip, increasing the density by 2 times compared with other solutions.
Ray Goggin, general manager of ADI's electronic test and measurement department, said: "the combination of performance and speed will bring more accurate and stable digital control loops, which can be stabilized at their final set points with lower delay. This ADC series reflects ADI's technological evolution. It further simplifies the process of design and evaluation, and can bring CNC precision instrument products to the market faster."
