具有增强的 PWM 抑制能力的 -4V 至 80V、双向、超精密电流感应放大器

INA240 器件是一款电压输出、电流检测放大器，具有增强型 PWM 抑制功能，可在独立于电源电压的 –4V 至 80V 宽共模电压范围内检测分流器电阻上的压降。负共模电压允许器件的工作电压低于接地电压，从而适应典型螺线管应用 的反激周期低功耗是一个关键问题。增强型 PWM 抑制功能可为使用脉宽调制 (PWM) 信号的系统（例如，电机驱动和螺线管控制系统）中的较大共模瞬变 (ΔV/Δt) 提供高水平的抑制。凭借该功能，可精确测量电流，而不会使输出电压产生较大的瞬变及相应的恢复纹波。\n\n该器件由 2.7V 至 5.5V 的单电源供电运行，消耗的最大电源电流为 2.4 mA。共有四种固定增益可 • 增强型 PWM 抑制功能\n• 132dB DC CMRR\n• 宽共模电压范围：-4V 至 80V\n• 增益： \n• 增益温漂：2.5ppm/°C（最大值）\n• 失调电压： \n• 温漂：250nV/°C（最大值）\n• 可用的增益： \n• INA240A2：50V/V\n• INA240A4：200V/V\n• 静态电流：2.4mA（最大值）;
