LMP8640 amplifier equivalent, precision high voltage current sense amplifier.
Typical values, TA = 25°C
* High common-mode voltage range -2V to 42V — LMP8640 -2V to 76V — LMP8640HV 2.7V to 12V
* Supply voltage range 20V/V; 50V/V; 100V/V
that demand accuracy over temperature. The LMP8640 and LMP8640HV come out with three different fixed gains 20V/V, 50V/V,.
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 common mode voltages with a supply voltage range from 2.7V to 12V. The LMP8640 accepts .
