ADI公司的AD4111是具有±10V和0 mA至20 mA输入和明线检测功能的低功耗 24 位 Σ-Δ ADC,集成了模拟前端(AFE),还集成主要模拟和数字的信号调理区快,为每个模拟输入通路配置成八种单独建立图,最大通路扫描速率6.2 kSPS(161 μs),嵌入的2.5V低漂移(5 ppm/℃)能隙基准电压降低了外接元件数量,单电源5V或3.3V工作,工作温度?40℃ 到 +105℃,主要用在过程控制PLC和DCS模块.本文介绍了AD4111主要特性,功能框图以及评估板EVAL-AD4111SDZ主要特性,框图,电路图,材料清单和PCB设计图.(The AD4111 is a low power, low noise, 24-bit, sigma-deltaanalog-to-digital converter (ADC) that integrates an analog front end (AFE) for fully differential or single-ended, high impedancebipolar,10 V voltage inputs, and 0 mA to 20 mA current inputs. The AD4111 also integrates key analog and digital signalconditioning blocks to configure eight individual setups for each analog input channel in use. The AD4111 features amaximum channel scan rate of 6.2 kSPS for fullysettled data.)
