The LMP8481MME-S/NOPB is a high-side precision Current Sense Amplifier that amplify a small differential voltage developed a cross a current sense resistor in the presence of high input common-mode voltages. This amplifier is designed for bidirectional current applications and accepts input signals with common-mode voltage range from 4 to 76V with a bandwidth of 270kHz. Because the operating power supply range overlaps the input common-mode voltage range, the LMP848x can be powered by the same voltage that is being monitored. This benefit eliminates the need for an intermediate supply voltage to be routed to the point of load where the current is being monitored, resulting in reduced component count and board space. The low-input offset voltage allows the use of smaller sense resistors without sacrificing system error.
