Part Number: LMP8480 Hi Team,
Could you help with the follow question from Samsung.
1. The LMP8480 device is powered by 5V. Under normal conditions, Vadc is less than 5V. However, in some cases, an increase in current can cause the differential input…
Part Number: LMP8481 Other Parts Discussed in Thread: LMP8480 Hello there,
I'm considering to replace LMP8480 with LMP8481 due to the stock. I just want to confirm : if I connects NC pins (pin 6 and 7) into GND (pin 4) with LMP8480, can I directly drop…
Part Number: LMP8480 Hi Team,
If VCC is 5V, how to calculate the Vsense?
Does it Vsense = 5V / Av ?
Besides, if VCC below 16V, the internal 14V LDO will not work. Am I right?
regards,
Johnson
Hi Israel,
Yes, I think a ground diode will protect LMP8480. You’ll have to consider/account for the voltage drop when measuring the output voltage.
If R215 and R216 are increased equally as R211, LMP8480 should survive as well. However the higher…
Hello User,
I need a little more information to attempt to help. Is there anyway during your test you exceed absolute max rating in the datasheet? If so then this will cause issues and . What exactly are your conditions on the LMP8480 and how do you…

I am investigating possible current sense solutions in our application. The input voltage is battery powered Vin: 10V ~ 40V and the…
Still blocked with Tina.
I added probe, like I said, other regular circuits works, this, including LMP8480 not.
I can't explain why don't you post a plot of your results.
Perhaps I do something wrong.
Part Number: LMP8480-Q1 Hi team
i need lowest input bias current for low power consumption.
LMP8480-Q1 D/S says Max 12uA per input.
may I get your reply ?
[1] so total input bias current will be 24uA(=12uA x 2) ?
[2] at VCC = 0V, may I know…
Dear Rohat, unfortunately that is the case for the LMP8480. As shown in section 9.1.1 of the datasheet, biasing the common mode below 4V introduces significant error into the part.
As such, I would not recommend this part if you need to drive the…

Hi team, What should I do to unused ALERT pin? OPEN? pull-up? GND? If ALERTpin connected to GND, are there any problems? Sincerely. Kengo.
