隔离放大器; ·VCM = 1000V 时达到 15kV/μs 共模抑制能力\n·紧凑可自动插入标准 8-pin DIP 封装\n·0.00025 V/V/°C 增益温度漂移\n·0.3mV 输入失调电压\n·100kHz 带宽\n·0.004% 非线性度\n·全球安全法规认证：\nUL 1577 (3750 Vrms/1 min)，CSA 和 IEC/EN/DIN EN 60747-5-2;

HCPL-7800A 隔离放大器系列主要面向电子电机驱动的电流感应设计。HCPL-7800A 可在实施典型驱动程序中检测电机电流通过外部电阻所产生的模拟电压降。并在 HCPL-7800A 光隔离屏障的另一端产生差分输出电压。这种差分输出电压与电机电流成正比，可以通过运算放大器转换成单端信号。由于现今的开关变频电机驱动系统中普遍存在共模电压在数十纳秒内出现几百伏摆幅的情况，因此 HCPL-7800A 采用可承受（最少 10 kV/μs）的超高共模瞬态变化压摆率的设计。\n\nHCPL-7800A 隔离型放大器 的共模瞬变抑制能力可在高噪声的电机控制环境下精确监测电机电流，其体现的精确性和稳定性足以为各类不同的电机控制应用提供较为平顺的控制（“转矩波动”较小）。\n\n这些产品还适于各类相当嘈杂的条件下需要高度精密性度、稳定性和线性度的通用模拟信号隔离应用。对于精密型应用，Broadcom 提供器件之间增益误差仅为 ±1% 的 HCPL-7800A。HCPL-7800A 采用 Σ-Δ 模数转换技术、斩波稳定放大器和全差分电路拓扑结构。\n\n这些功能的组合铸就了无与伦比的隔离模式噪声抑制能力以及卓越的失调修正性，即使在长时间与不同温度下仍可维持增益精确度和稳定性。这一性能通过紧凑型自动可插入产业标准 8 引脚 DIP 封装提供，而且符合全球安全法规标准。（另提供鸥翼型表面贴装方案 #300）。\n\n
