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-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-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-Q1 Hi team,
Regarding to datasheet of INA139-Q1, there is equations to calculate output voltage range. Does this equation cover all ambient temperature range? Is there any typical condition to apply this equation to the system?
Regards…
Part Number: INA139-Q1 Hi team
INA139-Q1 D/S says Input bias current = TYP 10uA.
so, total input bias current would be TYP 20uA(=10uA x 2) for two input pins ?
Other Parts Discussed in Thread: INA139-Q1 , INA169 , TINA-TI Dear, All
Customers are using the INA139-Q1. They are to insert a diode between GND and INA139-Q1's GND for protection reverse connection. Schematic diagram is as follows.
Because of this configuration…
Other Parts Discussed in Thread: INA139-Q1 I would like to confirm total output error of INA139-Q1.
I think the error includes the input offset voltage RTI too.
Is it correct?
Best regards,

Hi,
It is not recommended to adjust the gain externally. Please consider reducing the shunt resistor value as Kai suggested. In addition, we have the following lower gain options:
LMP8278-Q1 gain of 14; INA138-Q1, INA168-Q1, INA139-Q1 and INA169-Q1 with…
