LMP8640/LMP8640HV  
Precision High Voltage Current Sense Amplifier  
General Description  
Features  
The LMP8640 and the LMP8640HV are precision current  
sense amplifiers that detect small differential voltages across  
a sense resistor in the presence of high input common mode  
voltages with a supply voltage range from 2.7V to 12V.  
Typical values, TA = 25°C  
High common-mode voltage range  
LMP8640  
LMP8640HV  
-2V to 42V  
-2V to 76V  
2.7V to 12V  
The LMP8640 accepts input signals with common mode volt-  
age range from -2V to 42V, while the LMP8640HV accepts  
input signal with common mode voltage range from -2V to  
76V. The LMP8640 and LMP8640HV have fixed gain for ap-  
plications that demand accuracy over temperature. The  
LMP8640 and LMP8640HV come out with three different  
fixed gains 20V/V, 50V/V, 100V/V ensuring a gain accuracy  
as low as 0.25%. The output is buffered in order to provide  
low output impedance. This high side current sense amplifier  
is ideal for sensing and monitoring currents in DC or battery  
powered systems, excellent AC and DC specifications over  
temperature, and keeps errors in the current sense loop to a  
minimum. The LMP8640 and LMP8640HV are ideal choice  
for industrial, automotive and consumer applications, and it is  
available in TSOT-6 package.
