Part Number:INA826
Hi,
can you tell me if there is a mistake in the INA826 datasheet? They show a pin description at the beginning, but then, in the layout example in figure 73, the pinout is different.
It occurs that I had some PCBs built and the section depending on the INA826 does not work. That is how I came to post this question.
Thanks
Part Number:LM193
Is the LM193JG package (CDIP) max operating temperature is limted to 125C? As ceramic package can withstand higher temepratures (>175C) why the datasheet limits max operature temperature same as a plastic SOIC package.
Is the die design limiting this temperature not the package material?
Part Number:INA148
Hi,
I want to meassure the voltage but i have my battery about 1m away off board connected by wires. I measure the voltage on my board but i noticed a voltage drop over the distance which results in slower charging time. What can i do about this?
best regards,
Jonas

Hello.
We are looking for VCSEL driver solution for use with Finisar / HVS7000-004.
But Continuous current at inputs and outputs SPEC need up to 0.6 A~ 2.25A.
Do you have a suggest solution can provide to us? Thanks for kindly help~
Part Number:INA240
I need help selecting a current sense amplifier with the requirements below:
Small footprint is important, high side current solution can be considered (36V Bus) as well as options with integrated sense resistor.
Happy to discuss further for product roadmap & business case.
Part Number:LMV641
Hello,
Can you help clarify the closed loop gain from the LMV641 datasheet? In equation 4, it’s listed the required gain is 23.2 while in equation 6 where user calculate the max frequency, we advised to use the gain of 26.3. In the case of this example which should be the correct closed loop gain?
Thank you,
Raphael
Part Number:INA303
Hi,
I am currently working on a design and I am using the INA303A2. I an using the evaluation module INA303EVM (the one with 50V/V gain). Here is the schematic I am using, with some notes.
I have a 1mOhm sense resistor to measure the current. I am using this in a low side configuration, so IN- is connected to GND. I cannot figure out why, but using the INA303 in a low side configuration, as well as using a 0V reference voltage creates a delay on the output. For instance :
Blue is the output measured directly on the evaluation board (TP122) and teal is the voltage across the shunt resistor. As can be seen, it takes about 60us for the output to response. Please not that the delay vanishes if I use a reference of Vs/2 = 2.5V. I have not yet tried other values of reference voltage.
Interestingly, if I remove the shunt resistor and apply a waveform generator directly on the IN+ and IN- pins, the problem also vanishes. But as soon as I load the waveform generator enough, the common-mode voltage drops and the delay is back again. Also, increasing the frequency of the waveform generator decreases the delay.
All this leads me to think that this is a bias current issue. It seems to me like there is a minimum common-mode voltage needed to bias the inputs, or a non-zero reference voltage. I did not expect so however, as the datasheet states that the device can be used in both low-side or high-side configuration. The datasheet also specifies that the common-mode input range is -0.1 to 36V. But again, this is for a Vs/2 reference...
I will probably end up using a non-zero reference voltage, but I would like to know why this happens, and what minimum value of reference voltage I can use to avoid this delay. I'm using the INA303 for overcurrent detection, and ultimatly short-circuit protection, so a 60us delay to me is not acceptable.
I have already tried :
- Adding some filtering on the shunt resistor inputs (10ohms with 1000pF)
- Using a 2.5V reference as mentionned earlier. This does solve the problem. I haven't tried any other values.
- Changing the Ilimit or delay of the alert (Obviously this did not help)
Any help is greatly appreciated.
Thank you,
Olivier

The circuit diagram is as follows. The problem of U1D is that the three channels, U1DA, U1DC and U1DD, have consistent input signals but inconsistent output signals.Do you have any Suggestions?
Part Number:AMC1211-Q1
Tool/software:TINA-TI or Spice Models
The Input of AMC1211-Q1 is on module 1. The output of AMC1211-Q1 is on module 2. If Vdd1 is lost while Vdd2 is powered, what is the differential output level? I want the output to be zero. Currently I use ACPL-C78A. The output is 5V when Vdd1 is lost, which causes a lot of problems. I hope TI does not have this drawback.

I installed the Piezo Control Console (1.2.9) on to my Win 10 machine and it does not run?
Mu goal is to create a custom wave form so I can run my Piezo pump
Thanks

Part Number:TLV9062
Hello,
I am using the TLV9062D, but I only want to use one channel in some of my layouts, how do I need to connect the not used channel pins? to GND or leave them floating?
Thanks for checking that.

Part Number:PGA308
Hi,
I am trying to design a system to obtain the strain of a suspension system on an off-road baja vehicle, I was wondering if the PG308 would be the right amplifier to use for dynamic forces with large impulses. Would any additional circuits be needed or would the stain gauge directly input into the amp, with an analog out?
Thanks
Part Number:TLV3691
Hello,
The maximum Ibias shown in the data sheet is 20 nA across the full temperature range. In my application the allowable temperature range is -40C to 85C. I would like to find out if there is any data indicating the maximum Ibias within this smaller range or if there is any (conservative or otherwise) way to extrapolate a value.
Thanks,
Narek

Hi Support, Can I check if this part can be used to provide CP functions (constant power) ?
Does TI has a cross reference of ST FDA2100LV?
Thanks!
Part Number:OPA2381
Dear Specialists,
My customer is considering OPA2381 and has a question.
I would be grateful if you could advise.
---
Regarding output swing of OPA2381（Low）,
Could you please let you know the deviation of Voltage Output Swing from Negative Rail?（Could you please see in the red square）
(1) Could I think 50mV is three sigma?
(2) Is there temperature spec?（For example, Ta vs. Low output voltage）
(3) Is there a distribution data like a Figure of OFFSET VOLTAGE PRODUCTION DISTRIBUTION?

I appreciate your great help in advance.
Best regards,
Shinichi
Part Number:INA3221
Hi team,
Can you help to answer the question about the VPU pin:
1. What's the function of the VPU pin, does it need to connect the voltage we want to monitor?
2. If we don't supply any voltage to the VPU pin, does the PV pin will always show power invalid?
Lacey
Thanks a lot!

One of the two comparatos is not needed. Is there any recommendation on how to connect the unused pins?
