Hello Sai Ram,
This does seem like an AC CMRR issue. Please try the suggested. The 12V supply probed AC coupled on the scope should give you a good indication if you measure before and after adding capacitance and removing ferrite bead if this is the…
Part Number: LMP8640HV-HEVAL Other Parts Discussed in Thread: LMP8640 Hello E2E,
Our customer bought LMP8640HV-HEVAL. However, non HV version is mounted in EVM.
Is this the correct EVM? Can this EVM tolerate 60V input?
Regards, ACGUY

Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 We use LMP8640HVMKE-H/NOPB in sensing current (upto 3A) on a 48V DC rail. The sense resistor used is 8 mOhm to minimize the dc drop and power.
At low values of currents (~75mA), some of the…
Part Number: LMP8640HV I have a customer using LMP8640HV-F.
What's the max current the amp can source under the following conditions:
Sensing 20A through a .5mOhm shunt resistor
3.3V supply voltage.
The output loading is an RC filter into ADC of a…
Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 , Hello TI,
We use LMP8640 designed current monitor for pump. Currently has damaged MCU from U11 VOUT, and U11 damage issue when connector transient plugged in. Could you help us to recommended…
Part Number: LMP8640HV Hi,
My customer would like to use the LMP8640HV for a 60V application but they need to meet the IPC-2221B standard for conductor clearance. If I understand correctly, they would need 23.62 mils of clearance between external conductors…
Part Number: LMP8640HV Other Parts Discussed in Thread: INA181 , LMP8640 , INA240 Dear all,
I need a bi-directional current sensing amplifier pin compatible with LMP8640HV. Anyone help me please.
Part Number: LMP8640HV Other Parts Discussed in Thread: LMP8640 , LMP8601 , INA240 Hi everyone,
while running a current controlled valve, we noticed some unexpected signals at the output of the LMP8640HVMK-T. There are significant spikes every time the PWM…
Part Number: LMP8640HV Hello,
I will like to know please what the information on the NAMING OF LMP8640HV can be found.
I have looked in the datasheet and there is nothing about what the MKE prefix stands for.
I am particularly interested in the difference…
Part Number: LMP8640HV Other Parts Discussed in Thread: INA190 , INA225 Hi,
I am using the LMP8640HV IC for current sensing upto 5A with gain of 100. The issue is when no input voltage is applied to the op-amp, the output voltage is referenced at around…
