The  
LMP8481-Q1 devices are precision, high-side,  
current-sense amplifiers that amplify small

or  
unidirectional  
(LMP8480-Q1) current applications and accept input  
signals with a common-mode voltage range from 4 V  
to 76 V with a bandwidth of 270 kHz. Because the  
operating power-supply range overlaps the input  
common-mode voltage range, the LMP848x-Q1 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.  
Bidirectional or Unidirectional Sensing  
Common Mode Voltage Range: 4.0 V to 76 V  
Supply Voltage Range: 4.5 V to 76 V  
Fixed Gains: 20, 60, and 100 V/V  
Gain Accuracy: ±0.1%  
Offset: ±80 µV  
Bandwidth (–3 dB): 270 kHz  
Quiescent Current: < 100 µA  
Buffered High-Current Output: > 5 mA  
Input Bias Current: 7 µA  
The LMP848x-Q1 family consists of fixed gains of 20,  
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 LMP8480-Q1  
and LMP8481-Q1 are pin-for-pin replacements for the  
MAX4080 and MAX4081 devices, offering improved  
offset voltage, wider reference adjust range, and  
higher output drive capabilities. The LMP8480-Q1  
and LMP8481-Q1 are available in an 8-pin VSSOP  
package.
