Part Number: INA138-Q1 Hi team
INA138-Q1 D/S say Input bias current = Max 10uA.
so total input bias current would be Max 20uA(= 10uA x 2) for two input pins ?
further, may I know total input bias current for two input pins at Vs = 0V and common…

Part Number: INA138-Q1 Other Parts Discussed in Thread: INA138 Hi Team,
1. Is there any variation data of internal resistors(5kohm) at room temp?
2. Is internal resistor affected by ambient temp? If so, is there any data?
3. Is there any data…
Other Parts Discussed in Thread: INA281-Q1 , INA168-Q1 , INA138-Q1 There is no mention of any automotive qualification standard for INA170EA Current shunt in its datasheet, can we use it for automotive applications,
If not suggest us the alternate current…
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…
Shanthini, Thanks for bringing this to our attention. We will have the INA138 datasheet corrected in the next day and posted next week. In the meantime, if you need a correct pinout table you can use the INA138-Q1 datasheet. Sincerely, Peter Iliya
Part Number: INA270 Other Parts Discussed in Thread: LMP8278Q-Q1 , INA138 , LMP8645 Hi team, My customer is currently using the AD8208 for high-side current sensing and feeding its output into a 5V microcontroller. However, they are planning to switch…
Part Number: INA180-Q1 Other Parts Discussed in Thread: INA180 , INA138 , INA168 Tool/software: Hello team,
My customer found Iq linearly increased along with higher voltage, when bus voltage increases by 1V, the current consumption increases by 10uA…
Hello again,
We truly apologize for the weekend delay.
In order to scale the referenced design to higher voltages you need to:
1. Increase R3 to reduce unnecessary power loss.
2. Replace Z1 with a Zener that has a larger breakdown voltage < current…
