Analog Devices Inc. has released a new combination of next-generation 16- to 24-bit ultra-high-precision SAR ADCs. The new family of high-performance SAR ADCs features the company's patented Easy Drive technology and general-purpose flex-SPI SPI, addressing system design challenges, And expanded the selection of directly compatible ancillary products. It also simplifies the often complex process of designing ADCs into instrumentation, industrial and healthcare applications.
Easy Drive technology eliminates many traditional system-level design challenges such as strict layout guidelines, stringent digital interface timing requirements and complex companion product selection while maintaining device performance. The flexible spi digital interface simplifies the integration of the host processor and ADC by providing easy to meet timing requirements. The combination of high performance and this reimagined digital interface provides a better overall design experience while also speeding up the system design cycle.
First, in a family of 6 pin-compatible SAR ADCs, the 24-bit dual-channel, simultaneous sampling, 2Msps per second per channel AD4630-24 delivers an INL rating of 0.9ppm, a fourfold improvement over the others. The device combines the reference buffer and all key decoupling components into a single chip, resulting in a two-fold increase in solution density compared to other devices.
Ray Goggin, general manager of ADI's Electronic Test and Measurement Group said："The combination of performance and speed will result in a more accurate and stable digital control loop that can settle to final setpoint with lower latency," . ADI's new ADCs The Series is an intentional technological change that further simplifies the process of designing, evaluating and bringing digitally controlled precision instrumentation products to market faster.
