Description
General part information
LMP8645HV Series
The LMP8645 and the LMP8645HV devices are precision current sense amplifiers that detect small differential voltages across a sense resistor in the presence of high-input common-mode voltages.
Operating from a supply range of 2.7 V to 12 V, the LMP8645 accepts input signals with a common-mode voltage range of –2 V to 42 V, while the LMP8645HV accepts input signals with a common-mode voltage range of –2 V to 76 V. The LMP8645 and LMP8645HV have 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. The LMP8645 is an ideal choice for industrial, automotive, and consumer applications, and is available in SOT-6 package.
