Part Number: INA139 Hello team,
I want to clearify the terms in datasheet.
In the datasheet, the total output error is +/- 2% (max). What is total output error mean? Is this output current error, including all the offsets, gain errors, etc?
Best Regards…
Part Number: INA139 Other Parts Discussed in Thread: INA199 Hi,
I'm choosing a current sense amp.
INA139's GAIN can be set by external RL.
INA199's GAIN is fixed with different version.
When should I choose INA139 and when should I choose…

Hello E2E,
Good day.
Our customer will use INA139 to read voltage and current values. The input voltage is 7- 28V. The circuit schematic is as shown. Is there any missing or problem in the circuit?
Regards, Carlo
Part Number: INA139-Q1 Other Parts Discussed in Thread: TL074 , INA139 , INA293-Q1 ,
I have a big problem with the INA139-Q, I am using a shunt resistor of 1.5mOhms that returns 75mV@50A. However, I can´t test my circuit with 50 A, so I am trying just with…
Part Number: INA139 Hi,
Our design uses INA139 for sensing currents around 80-100A.
For the current sense resistor, we are using multiple (3 Nos) resistors in parallel.
Pl share the placement & routing guidelines for the application which uses multiple…
Part Number: INA139 Hi,
We are having issues with current shunt monitor INA139. We have been using this part for the past 8 years or so with yearly volume of about 2K. We need to rework our boards to replace INA139 in order to measure the current accurately…
Part Number: INA139 Hi team,
The datasheet of INA139 shows table for RL selection to set the gain.
From my understanding, Gain=RL/1k. And using resistors not listed in the table is fine.
So if I want to set the gain as 13.5, using 13.5kohm (or nearest…
Part Number: INA139-Q1 Other Parts Discussed in Thread: INA139 Hi sir,
I have some queries on this device need your verification.
1.is there a problem if I input an analog input signal before the power turning on?
2.How much is the resistance tolerance value…
Part Number: INA139 Dear Specialists,
My customer is considering INA139 and has a question.
I would be grateful if you could advise.
