TEXAS INSTRUMENTS  LMP8645MKE  电流检测放大器, 高电压, 1个放大器, 23 µA, TSOT, 6 引脚, -40 °C, 125 °C

The is a high-speed voltage output Current Sensing Amplifier that detects small differential voltages across a sense resistor in the presence of high-input common-mode voltages. Operating from a supply range of 2.7 to 12V, the LMP8645 accepts input signals with a common-mode voltage range of -2 to 42V. The LMP8645 has adjustable gain for applications where supply current and high common-mode voltage are the determining factors. The gain is configured with a single resistor, providing a high level of flexibility, as well as accuracy as low as 2% maximum including the gain setting resistor. The output is buffered to provide low output impedance. This high-side current sense amplifier is ideal for sensing and monitoring currents in DC or battery-powered systems, has excellent AC and DC specifications over temperature and keeps errors in the current sense loop to a minimum.
