ADICN0292工业级四路数据采集系统方案
资料介绍
ADI公司的CN0292是全隔离的工业级四路数据采集系统，主要采用AD7176-2高分辨率24位Sigma-Delta ADC，AD8476全差分输入和输出放大器，ADA4096-4四路运算出放大器，ADA4898-1超低功耗运算放大器，ADG1204模拟复接器以及ADP1720低压降线性稳压器，主要用在仪表，PLC/分布控制系统，测试和测量.本文介绍了工业级四路数据采集系统主要电路描述，电路框图，测试
建立功能框图，详细电路图，材料清单和PCB设计文件.
The circuit in Figure 1 is a completely isolated，robust，industrial，4-channel data acquisition system that provides 16-bit，noise free code resolution and an automatic channel switching rate of up to 42 kSPS.The channel to channel crosstalk at 42 kSPS switching is less than 15 ppm FS（less than-90 dB）because of the unique selection of fast settling components in the multiplexed signal chain.The circuit acquires and digitizes standard industrial signal levels of 5V，10V，0 Vto 10wand 0mA to 20 mA.The input buffers also provide overvoltage protection，thereby eliminating the leakage errors associated with conventional Schottky diode protection circuits.
