Part Number: INA148 At present, I have a project to use ina148 chip again. During the use, the sampling output value drifts. The output value jitters about 0.2V. The attachment is the schematic diagram and ina148 output waveform for reference.

Part Number: INA148 Hi All,
One of my customer is using the INA148 in single supply 12V application, Vref=0V.
What is the CM range, specifically low-limit common-mode input voltage?
Also any issue with the output swinging up to 10.5V.
Thanks,
Regards…

Dear Luis, thank you
Please, see my previous thread and your answer.
Point is that, I do not need high measurement accuracy. Error 10-15% will suit me.
In fact, the signals, transmitted on this line, are pulsed signals with a duration…

I need to receive signals from two wire line, please, see attach.
I think it would be right to put INA148 at the input of the line (at the input of the…
Part Number: INA149 Other Parts Discussed in Thread: INA148 Tool/software: Hello,
Can you provide the details for deriving the equations in the INA149 d/s specifically equations 1 and 2:
Thanks, Adam
Part Number: INA148 Hello, Is an input voltage of 15V (between Vin+ an Vin-) allowed if there is no supply voltage? The supply voltage and Ref is on ground.This could happen, if we perform a high voltage test on the board. The INA148 is connected to…
Part Number: INA149 Other Parts Discussed in Thread: INA148 Tool/software: Hi TIer
It is desired to find a rail where the AMP monitors the 400-V common-mode voltage. I see that our products have a maximum tolerance of the common mode voltage of the INA149…
Part Number: INA148 Other Parts Discussed in Thread: INA146 Hi
I did not found the output resistance in the DS of INA148, where could I find the value ? I would like to detect battary 4.2V voltage, and using resistances to divide the 4.2 to the range…

Dear Marek, thank you
I, probably, will use INA148 for receiving signal from a two-wire line. I have a long two-wire line - more than 10 km.
Please, report
1) What max DIFFERENTIAL input voltage…
Part Number: INA148 Other Parts Discussed in Thread: ISO124 , INA240 Hello,
Our application can be described using 2 images.
Case 1:
Doubt related to this case: Will the IC work as expected even if Ref = 0V. What will be the CMV range in this case, as…
