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 LMP8645HV accepts input signals with a common-mode voltage range of -2 to 76V. The LMP8645HV 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.
