环路供电4-20 mA传感器发射机

AD693是一款单芯片信号调理电路，可从各种传感器接受低电平输入来控制标准4-20 mA双线电流环路。它提供片内基准电压源和辅助放大器进行传感器激励；当器件以环路供电模式工作时，激励电流最高可达3.5 mA。或者，当需要0-20 mA电源时，器件可通过本地供电实现三线应用。\n\n通过简单的引脚绑定，可设置预先校准的30 mV和60 mV输入范围。还可添加外部电阻，实现从1 mV至100 mV的其他范围。辅助放大器可结合片内电压，为100Ω RTD提供六种预先校准范围。还可通过引脚绑定确定输出范围和零输出，从而获得标准范围：4-20mA、12 ± 8 mA和0-20 mA。 \n\n对AD69 • 仪表放大器前端 \n\n• 环路供电电源 \n\n• 可独立调整的输出范围和零输出 \n\n• 预先校准的输出范围:\n4-20 mA单极性\n0-20 mA单极性\n12 ± 8mA双极性\n\n• 预先校准的20 mV或60mV输入范围 \n\n• 预先校准的100 O RTD接口\n\n• 6.2 V 基准电压源，可提供高达3.5 mA的电流 \n\n• 非专用辅助放大器，提供更高灵活性\n\n• 可选的外部调整管，可减少自热误差;
