ADI's New Easy Drive SAR ADC Simplifies Design and Delivers Leading Performance

     Analog Devices, Inc introduced a new generation of 16 to 24 bit ultra-high precision successive approximation register (SAR) analog-to-digital converter (ADC) series products, which can simplify the complex ADC design in instrumentation, industrial and medical health applications. The new high-performance SAR ADC series uses Easy Drive patented by ADI ™ The technology and the universal Flex 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 Flex SPI digital interface provides easy to meet timing requirements, simplifying the integration of host processors and ADC. The combination of high performance and this re conceived digital interface provides a better overall design experience, and also speeds up the system design cycle.

     The first in this series of six pin-compatible SAR ADCs is the 24-bit dual-channel synchronous sampling AD4630-24 with 2 Msps per channel, which provides the leading accuracy (INL) with a rating of 0.9 ppm, four times higher than other solutions. The AD4630-24 integrates the benchmark buffer and all key decoupling elements into a single chip, resulting in a 2x density increase compared to other solutions.

     "The combination of performance and speed will result in a more accurate and stable digital control loop that can be stabilized at its final set point with lower latency," said Ray Goggin, general manager of ADI's Electronic Test and measurement division. "The ADCs represent ADI's technological evolution to further simplify the design, evaluation process and bring CNC precision instruments to market faster."
