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…
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: 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…
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…
