AD7631是一款18位、电荷再分配、逐次逼近型 (SAR)架构模数转换器(ADC),采用ADI公司的iCMOS高电压工艺制造。该器件的输入范围和工作模式可通过硬件或专用只写串行配置端口来配置。AD7631内置一个18位高速采样ADC、一个内部转换时钟、一个内部基准电压源(和缓冲)、纠错电路,以及串行和并行系统接口端口。在CNVST的下降沿,对IN+和IN−上的全差分模拟输入进行采样。AD7631具有四种不同的模拟输入范围,功耗与吞吐量呈线性比例关系,工作温度范围为−40°C至+85°C。
The AD7631 is an 18-bit, charge redistribution, successive approximation register (SAR), architecture analog-to-digital converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage process. The device is configured through hardware or via a dedicated write-only serial configuration port for input range and operating mode. TheAD7631 contains a high speed 18-bit samplingADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. A falling edge on CNVST samples the fully differential analog inputs on IN+ and IN−. The AD7631 features four different analog input ranges. Power is scaled linearly with throughput. Operation is specified from −40°C to +85°C.
