Part Number: LMP8645 Is the TI spice model for the LMP8645 wrong? Using TI spice, I get an unexpectedly large offset error; I didnt expect this for a part with specs of Vos = 1mV and Ib = 23uA.
Using high side current sensing through a .005 ohm sense resistor…
Part Number: LMP8645 Other Parts Discussed in Thread: TPS65132 In our a project , we use LMP8645 to detect the current of DCDC output . The output voltage of DCDC is 1.8V .
LMP8645 is connected after the DCDC output .
Test condition : The input of DCDC…
Part Number: LMP8645 Hi there,
I am using LMP8645 for a low-side current sense application as shown in the attached schematic. The current is a high-frequency diode-rectified unipolar current and I am trying to get the average of it. Therefore I have…
Part Number: LMP8645 HI E2E
Please let me know the voltage that can be applied to each of +IN and -IN.
For example, V+ is connected to +5V, and V- is connected to ground, is the voltage that can be applied to +IN and -IN up to +5V?
Best Regards.
Part Number: LMP8645 Other Parts Discussed in Thread: LMP8481 , , INA240 Hello,
I’m looking at using the LMP8645/8640, but it lacks the reference input of the LMP8481.
Is there a similar part that has a reference voltage input? This would allow us…
Part Number: LMP8645 Dear All,
In a WPT project, I'm making a feedback with a LMP8645 on the feedback pin of a DCDC buck regulator. The voltage on this pin is Vfb=0.6V during regulation
The objective is to increase or decrease the DCDC voltage accordingly…
Part Number: LMP8645 Other Parts Discussed in Thread: INA190 The load is powered by dcdc,and the maximum current of the load is limited to 7mA,so can LMP8645 limit the current below 7mA? And what the accuracy is?
Part Number: LMP8645LMP8645 datasheet is described absolute max rating of +Vin - (-Vin), but only max: 6V.
Please let me know about Min voltage range.
I think that min voltage range is a little negative voltage, for example -0.3V, correct?
Or, is 0V…
Part Number: LMP8645 Hi,
After I'm connecting LMP8645 with 3.3v at the V+ and 0v at V-. I can measure 1.5v at +in and -in terminals. According to my understanding I should see a small floating voltage on those terminals but not something as high as 1…
Other Parts Discussed in Thread: LMP8645 , TINA-TI , LMP8646 Hello,
I want to simulate LMP8645 (current sensing amplifier) using TI Tina. In the datasheet it states that SNOM087 is the Tina spice model, but I cannot find the model from Tina. Can you please…
