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. The gain is configured with a single resistor, providing a high level of flexibility, the accuracy could be as low as 2% (max) including the gain setting resistor. The output is buffered in order to provide low output impedance. This high side current sense amplifier is ideal for sensin
