Hi,
It is not recommended to adjust the gain externally. Please consider reducing the shunt resistor value as Kai suggested. In addition, we have the following lower gain options:
LMP8278-Q1 gain of 14; INA138-Q1, INA168-Q1, INA139-Q1 and INA169-Q1 with…
Part Number: LMP8603-Q1 Other Parts Discussed in Thread: LMP8601-Q1 , LMP8601 , LMP8602-Q1 , LMP8602 , LMP8603 , Hi,
I am planning to use this part to monitor the current flowing into a negative power supply. While reading the datasheet, I am a bit confused…
Part Number: LMP8603-Q1 Other Parts Discussed in Thread: LMP8602 , LMP8601 , LMP8603 Thank you Javier for your reply and your advice on the dependency of the input impedance wrt the Vcm. Much appreciated.
One more question is about the figures (Figure49…
Hello Nobuo,
Thanks for reaching out on the forum. I am investigating your issue right now. I suspect your issue is similar to the issue found for the lmp8601 in this e2e post . As such, I do not think you will have the option to adjust the gain when you…
Hi,
It is fine to add the Schottky diodes, although their effectiveness depends on the forward conducting voltage versus current. Some of these parasitic inductances are out of user’s control, but some are, such as L6. Therefore a compact minimal loop…

Part Number: INA260 Other Parts Discussed in Thread: AMC1300 , LMP8601 Hi Sir,
INA260 is 36V current Monitor,
Do you know TI have AC 24V current Monitor?

Hello Simon,
Thanks for considering to use Texas Instruments in your design. This behavior is something that is revealed through simulation or bench tests. CMRR does contribute as you noted that the dips disappear with the low-side configuration. …
Hi Tejas,
I assume the LMP8601 is placed in series with the LED line somewhere. How much offset are you seeing? Does the offset go away if you remove the LMP8601 and just measure the voltage across RL to measure current?
The LMP8601 has several microamps…
