AD7861: 11位分辨率同时采样ADC

AD7861是一款多通道同时采样模数转换器(ADC),用于马达控制解决方案或三相式电源系统中的电压输入信号采集。该器件结合ADI公司的16位定点数字信号处理器(DSP),可提供低成本的16位定点微控制器解决方案。输入级经过特别设计,可处理马达驱动器中常见的信号类型。VIN1、VIN2和VIN3通道均为同时采样输入,适合进行电机定子电流采集。AUX0–AUX3通道为多路复用通道,适合慢速运动输入,例如马达控制应用中的温度和二极管整流器输出的总线电压等。

The AD7861 is a multichannel simultaneous sampling A/D Converter (ADC) configured for the acquisition of voltage inputs in a motor control solution or three-phase power system.The AD7861 combined with Analog Devices’ 16-bit fixed-point digital signal processor (DSP) provides a low cost 16-bit fixed-point microcontroller solution. The input stage has been designed to accommodate the types of signals frequently found in motor drives. The VIN1, VIN2, and VIN3 channels are simultaneously sampled inputs suitable for stator current acquisition. The AUX0–AUX3 channels are multiplexed and are suitable for slower moving inputs such as temperature and bus voltage of the diode rectifier output in a motor control application.
