LT1999 - 高电压、双向电流检测放大器 - Linear Technology（凌力尔特）
功能描述
LT1999 是一款高速、精准的电流检测放大器，专为在一个宽共模范围内监视双向电流而设计。LT1999 可提供三种增益选项：10V/V、20V/V 和 50V/V。
LT1999 通过一个外部阻性分路器来检测电流，并产生一个输出电压，可指示检测电流的数值和方向。输出电压以位于电源电压与地之间的中间电压为参考电位，或者也可以采用一个外部电压来设定参考电平。LT1999 具有一个 2MHz 带宽和一个 –5V 至 80V 的共模输入范围，因而适合于监视 H 桥电机控制器中的电流、开关电源、螺线管电流、以及电池充电电流 (从满充电至电量耗尽)。
LT1999 采用一个独立的 5V 工作电源，并吸收 1.55mA 电流。该器件提供了一种停机模式以最大限度地降低功耗。
LT1999 可提供 8 引脚 SOP、8 引脚 MSOP (原有引脚) 或专为 FMEA 的 8 引脚选项。
