LMP8645/LMP8645HV Precision High Voltage Current Sense Amplifier January 7, 2010 LMP8645/LMP8645HV Precision High Voltage Current Sense Amplifier General Description The LMP8645 and the LMP8645HV 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 2.7V to 12V. The LMP8645 accepts input signals with common mode voltage range from -2V to 42V, while the LMP8645HV accepts input signal with common mode voltage range from -2V to 76V. The LMP8645 and LMP8645HV have adjustable gain for applications where supply current and high common mode voltage are the determining factors.
