AD7612是一款16位电荷再分配逐次逼近型寄存器(SAR)架构的模数转换器(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。AD7612内置一个16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,它对IN+和IN-之间的电压差进行采样。AD7612具有四种不同的模拟输入范围和三种不同的采样模式:Warp模式适用于最高吞吐量,正常模式适用于最高异步吞吐量,而在脉冲模式下,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 AD7612 is a 16-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. The AD7612 contains a high speed 16-bit sampling ADC, 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 analog input on IN+ with respect to a ground sense, IN–. The AD7612 features four different analog input ranges and three different sampling modes: warp mode for the fastest throughput, normal mode for the fastest asynchronous throughput, and impulse mode where power consumption is scaled linearly with throughput. Operation is specified from −40°C to +85°C.
