LMP8601/LMP8601Q  
60V Common Mode, Bidirectional Precision Current  
Sensing Amplifier  
General Description  
Features  
The LMP8601 and LMP8601Q are fixed 20x gain precision  
amplifiers. The part will amplify and filter small differential sig-  
nals in the presence of high common mode voltages. The  
input common mode voltage range is –22V to +60V when op-  
erating from a single 5V supply. With 3.3V supply, the input  
common mode voltage range is from –4V to +27V. The  
LMP8601 and LMP8601Q are members of the Linear Mono-  
lithic Precision (LMP®) family and are ideal parts for unidirec-  
tional and bidirectional current sensing applications. All  
parameter values of the part 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 = 20x

All Min / Max limits 100% tested  
The part has a precise gain of 20x which is adequate in most  
targeted applications to drive an ADC to its full scale value.  
The fixed gain is achieved in two separate stages, a pream-  
plifier with a gain of 10x and an output stage buffer amplifier  
with a gain of 2x. The connection between the two stages of  
the signal path is brought out on two pins to enable the pos-  
sibility 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 applica-  
tions section .  
Applications  
High side and low side driver configuration current sensing

Bidirectional current measurement  
Current loop to voltage conversion  
Automotive fuel injection control  
Transmission control  
Power steering  
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 .  
Battery management systems  
The LMP8601Q incorporates enhanced manufacturing and  
support processes for the automotive market, including defect  
detection methodologies. Reliability qualification is compliant  
with the requirements and temperature grades defined in the  
AEC Q100 standard.
