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.
---
We're considering to apply 0V to pin 5 (V +) of INA139 and -12V to pin 2 (GND) to output a negative voltage.

Dear colleague,
Our customer is planning to do a design in the brick power module for preventing current backflow. The previous solution is a diode, but as the power rate increases, a diode has more power dissipation. So we want to use…
Part Number: INA139 Other Parts Discussed in Thread: INA170 Hi there
I'm following up on a test related to the INA139 and simulations in TI-TINA.
The current that I want to take to sample is from -2.5 A to +2.5 A, and the frequency is range from 100K…
Part Number: INA139-Q1 Other Parts Discussed in Thread: INA139 Hi team,
Our customer asked a question about INA139Q1.
Could you support to answer these questions?
1. I want to know the internal circuit between PIN 8 and PIN6 in INA139-Q1 for DFMEA analysis…
So the measured voltages are between 10 mV and 60 mV. The amplifier's input offset error should be much smaller than this; the OPA2291-Q1 would be fine.
But a difference amplifier circuit is sensitive to resistor tolerances; if you care about accuracy…
Part Number: INA139 Other Parts Discussed in Thread: INA190 , INA191 , INA186 Hi,
I have referred to the datasheet and found that there is a VOUTMAX which indirectly imposes a limitation on current measurement.
My application would be to have this on different…
Part Number: INA139 Other Parts Discussed in Thread: INA271 , INA282 , INA283 Hello Sir,
Good Evening,
This is Eazhil Having some doubt with Current sensor INA139 SOT23-5. Previously i'm using INA271 SOIC Package for High side current sensor for my circuit…
Part Number: INA139 Other Parts Discussed in Thread: INA240 I have two questions about INA139. The first one is : Can i use the INA139 with a differential input voltage range from 100mv and 1.5V? How does it operate in this situation?
.
The second…
