DESCRIPTION  
The LMP8480 and LMP8481 are precision high-side current sense amplifiers that amplify a small differential  
voltage developed across a current sense resistor in the presence of high input common-mode voltages.  
These amplifiers are designed for bidirectional (LMP8481) or unidirectional (LMP8480) current applications and  
will accept input signals with common-mode voltage range from 4V to 76V with a bandwidth of 270 kHz.  
Since 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 LMP848x family consists of fixed gains of 20, 50, 60 and 100 for applications that demand high accuracy  
over temperature. The low input offset voltage allows the use of smaller sense resistors without sacrificing  
system error.  
The wide operating temperature range of -40C to 125C makes the LMP848x an ideal choice for automotive,  
telecommunications, industrial, and consumer applications.  
The LMP8480 and LMP8481 are pin for pin replacements for the MAX4080 and MAX4081, offering improved  
offset voltage, wider reference adjust range and higher output drive capabilities.  
The LMP8480 and LMP8481 are available in a 8-pin MSOP package and the LMP8481 is also available in a  
8–pad LLP.
