LMP8602/LMP8603  
60V Common Mode, Fixed Gain, Bidirectional Precision  
Current Sensing Amplifier  
General Description  
Features  
The LMP8602 and LMP8603 are fixed gain precision ampli-  
fiers. The parts will amplify and filter small differential signals  
in the presence of high common mode voltages. The input  
common mode voltage range is –22V to +60V when operating  
from a single 5V supply. With a 3.3V supply, the input com-  
mon mode voltage range is from –4V to +27V. The LMP8602  
and LMP8603 are members of the Linear Monolithic Precision  
(LMP®) family and are ideal parts for unidirectional and bidi-  
rectional current sensing applications. All parameter values  
of the parts that are shown in the tables are 100% tested and  
all bold values are also 100% tested over temperature.  
Unless otherwise noted, typical values at TA = 25°C,  
VS = 5.0V, Gain = 50x (LMP8602), Gain = 100x (LMP8603)

All Min / Max limits 100% tested  
The parts have a precise gain of 50x for the LMP8602 and  
100x for the LMP8603, which are adequate in most targeted  
applications to drive an ADC to its full scale value. The fixed  
gain is achieved in two separate stages, a preamplifier with a  
gain of 10x and an output stage buffer amplifier with a gain of  
5x for the LMP8602 and 10x for the LMP8603. The connection  
between the two stages of the signal path is brought out on  
two pins to enable the possibility to create an additional filter  
network around the output buffer amplifier. These pins can  
also be used for alternative configurations with different gain  
as described in the applications section.  
Applications  
High side and low side driver configuration current sensing

Transmission control  
Power steering  
Battery management systems  
■
The mid-rail offset adjustment pin enables the user to use  
these devices for bidirectional single supply voltage current  
sensing. The output signal is bidirectional and mid-rail refer-  
enced when this pin is connected to the positive supply rail.  
With the offset pin connected to ground, the output signal is  
unidirectional and ground-referenced.  
The LMP8602 and LMP8603 are available in a 8–Pin SOIC  
package and in a 8–Pin MSOP package.
