LMP8640/LMP8640HV Precision High Voltage Current Sense Amplifier September 7, 2010 LMP8640/LMP8640HV Precision High Voltage Current Sense Amplifier General Description The LMP8640 and the LMP8640HV are precision current sense amplifiers that detect small differential voltages across a sense resistor in the presence of high input mon mode voltages with a supply voltage range from 2.7V to 12V. The LMP8640 accepts input signals with mon mode voltage range from -2V to 42V, while the LMP8640HV accepts input signal with mon mode voltage range from -2V to 76V. The LMP8640 and LMP8640HV have fixed gain for applications that demand accuracy over temperature. The LMP8640 and LMP8640HV...
