Descripción de LMP8640HV
The LMP8640, LMP8640-Q1 and the LMP8640HV are precision current sense amplifiers that detect small differential voltages across a sense resistor in the presence of high input common mode voltages with a supply voltage range from 2.7 V to 12 V.
The LMP8640 and LMP8640-Q1 accept input signals with common mode voltage range from –2 V to 42 V, while the LMP8640HV accepts input signal with common mode voltage range from –2 V to 76 V. The LMP8640 and LMP8640HV have fixed gain for applications that demand accuracy over temperature. The LMP8640 and LMP8640HV come out with three different fixed gains 20 V/V, 50 V/V, 100 V/V ensuring a gain accuracy as low as 0.25%. The output is buffered in order to provide low output impedance. This high side current sense amplifier is ideal for sensing and monitoring currents in DC or battery powered systems, excellent AC and DC specifications over temperature, and keeps errors in the current sense loop to a minimum. The LMP8640 and LMP8640HV are ideal choice for industrial and consumer applications, while the LMP8640-Q1 is an AEC-Q100 grade 1 qualified version of the LMP8640 for automotive applications. The LMP8640-x is available in SOT-23-6 package.
