Analog Devices Inc. AD7176-2 西格玛-德尔塔型模数转换器
Analog Devices AD7176-2是一款24位250kSPS西格玛-德尔塔型模数转换器(ADC)，其吞吐速率可达替代性西格玛-德尔塔型转换器的两倍，且功率耗散更低。ADI AD7176-2 专为数据通道密度高、通道监测速度快的过程自动化和仪器系统而设计，其多通道扫描速率可达50kSPS。在自动化高精度生产线应用中，AD7176-2 凭借西格玛-德尔塔结构固有的强大性能，可在加快生产速度的同时，实现精准低输入带宽信号测量。单通道测量时，AD7176-2 在250kSPS 时具有17.2位无噪声分辨率，5SPS 时为22位无噪声分辨率。 EVAL-AD7176-2SDZ 是针对AD7176-2的全功能评估套件，可单独使用，也可与系统开发平台 EVAL-SDP-CB1Z配合使用。
In an automated, high-precision production line, the performance of AD7176-2 allows for faster manufacturing while achieving the precision, low-input bandwidth signal measurements that are inherently associated with the sigma-delta architecture. Measured on a single channel, AD7176-2 delivers as many as 17.2 noise-free bits at 250kSPS and 22 noise-free bits at 5SPS.
