【产品】隔离式运放CA-IS1200用于电流检测,支持符合UL1577认证的高达3750VRMS的电气隔离
CA-IS1200器件是为基于分流电阻的电流检测而优化的高精度隔离式运放。低的失调和增益误差以及相关温漂能够在全工作温度范围内保持测量的精度。
CA-IS1200器件采用二氧化硅(SiO2)作为隔离层,支持符合UL 1577认证的高达3750VRMS的电气隔离。该技术将高低压域分开从而防止低压器件被损坏,同时提供低辐射和高磁场抗扰度。高共模瞬态抗扰度(CMTI)意味着CA-IS1200器件在隔离层之间正确地传递信号,适合要求高压、大功率开关的工业电机控制和驱动应用场合。器件内部输入共模过压和高边电源丢失检测功能有助于故障诊断和系统安全。
CA-IS1200器件通过八脚DUB封装,封装尺寸(标称值)9.20 mm × 6.35 mm,支持在额定扩展工业温度范围内(–40°C到125°C)正常工作。

【选型】增益误差低至±0.3%的高精度隔离式运放用于光伏逆变器,可替代TI的AMC1200
在光伏逆变器应用中,通常会采用隔离放大器加精密电阻来进行电流采样,隔离放大器把强电部分和控制部分隔离开,保证了电路的安全和精密的信号传输。客户原来打算采用TI的AMC1200,现需要国产替代。本文推荐川土微电子的CA-IS1200用来替代AMC1200。
