精密微型隔离放大器

ACPL-790B/790A/7900 精密微型隔离放大器是专为电机驱动器和可再生能源系统等电子大功率变流器中的电流和电压感测而设计的。 在实施典型的电机驱动程序中，隔离放大器可检测到电机电流通过外部电阻所产生的模拟电压降。光隔离屏障的另一端则产生差分正比于电机电流的差分输出电压。建议在通用型应用中采用（±1% 增益误差）的 ACPL-790A 和（±3% 增益误差）的 ACPL-7900。对于高端精密型应用，需采用（±0.5% 增益误差）的 ACPL-790B。该产品采用 5V 单电源供电，具备优异的线性度和 60 分贝的信噪比动态性能。由于具有 200 kHz 带宽 ·0.5% 高增益精度（仅 ACPL-790B）\n·–50 ppm/°C 低增益漂移\n·0.6 mV 输入失调电压\n·0.05% 出色的线性度\n·60 dB 信噪比\n·200 kHz 宽频带宽\n·输出 3V 至 5.5V 的宽范围电压\n·–40°C 到 +105°C 工作温度范围\n·先进的 Sigma-Delta (Σ-Δ) 模数转换技术\n·全差分隔离放大器\n·15 kV/µs 共模瞬变抑制能力\n·紧凑的自动插入扩展型 SO-8 封装\n·安全规范认证（申请中）：\n- IEC/EN/DIN EN 60747-5-5: 891 Vpeak 工作绝缘电压\n;
