FEATURES  
DESCRIPTION  
The LMP8640 and the LMP8640HV are precision

Typical Values, TA = 25°C  
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.

Max Gain Error: 0.25%  
The LMP8640 accepts input signals with common  
mode voltage 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 applications that  
demand accuracy over temperature. The LMP8640  
and LMP8640HV come out with three different fixed  
Low Offset Voltage: 900µV  
Input Bias Current: 13 µA  
PSRR: 85 dB  
gains 20V/V, 50V/V, 100V/V ensuring  
a gain  
CMRR (2.1V to 42V): 103 dB  
Temperature Range: -40°C to 125°C

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 SOT-6  
package.
