LMP8640/-Q1/HV Precision High Voltage Current Sense Amplifiers  
1 Features  
3 Description  
The LMP8640, LMP8640-Q1 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 2.7 V to 12 V.

Typical Values, TA = 25°C  
High Common-Mode Voltage Range  
LMP8640: -2 V to 42 V  
LMP8640-Q1: -2 V to 42 V, AEC-Q100  
LMP8640HV: -2 V to 76 V  
The LMP8640 and LMP8640-Q1 accept input signals  
with common mode voltage range from -2 V to 42 V,  
while the LMP8640HV accepts input signal with  
common mode voltage range from -2 V to 76 V. The  
LMP8640 and LMP8640HV have fixed gain for  
applications that demand accuracy over temperature.  
The LMP8640 and LMP8640HV come out with three  
different fixed gains 20 V/V, 50 V/V, 100 V/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  
Supply Voltage Range: 2.7 V to 12 V  
Gain Options: 20 V/V; 50 V/V; 100 V/V  
Max Gain Error: 0.25%  
Low Offset Voltage: 900 µV  
Input Bias Current: 13 µA  
PSRR: 85 dB  
CMRR (2.1V to 42V): 103 dB  
Temperature Range: -40°C to 125°C

specifications over temperature, and keeps errors in  
the current sense loop to a minimum. The LMP8640  
and LMP8640HV are ideal choice for industrial and  
consumer applications, while the LMP8640-Q1 is an  
AEC-Q100 grade 1 qualified version of the LMP8640  
for automotive applications. The LMP8640-x is  
available in SOT-23-6 package.
