Part Number: INA4181-Q1 Other Parts Discussed in Thread: TLV9002-Q1 Tool/software: Hi team,
My customer wants to know what's the benefit of current sensing amplifier (INA4181-Q1) over general purpose amplifier (TLV9002-Q1). Besides the saving of external…
Hey JH,
You could open up IN+ pin to reduce overall power consumption. The disadvantage is that you will significantly increase offset error (make input offset, Vos, more negative) due to PMOS drain-to-source voltage.
If you can calibrate out the offset…
Part Number: INA4181 Hi experts,
Good day!
INAx181 family has different BW.
1. I would like to know the experience on how to choose enough BW device.
2. Customer is evaluating it in micro inverter, the switching frequency is 120khz, how to choose enough…

Part Number: INA4181 Hello,
I'd like to know how to design pin connection for unused channel in INA4181. (For example, 3/4 channel are used and 1/4 is unused.) 1) IN-x 2) IN+x 3) OUTx 4) REFx
Thanks in advance. S.Sawamoto
Hello Appreciated Engineer,
The INA4180 is unidirectional. It cannot measure bidirectional current. The INA4181 is bidirectional because it has a REF pin which can bias the output voltage out of GND saturation when load = 0A.
Could you try the INA4181…
Part Number: INA2181-Q1 What would be the expected thermal stability /drift of the Gain value when external resistors are added at the inputs of these amplifiers for filtering? (For example, two 10-Ohm resistors, per datasheet example at 9.1.3 Signal …
Part Number: INA4180 Other Parts Discussed in Thread: INA180 , INA240 Hi Team,
Would it be okay to use a 100kohm resister and 100nF capacitor at the input for low drive application. I read that for high side we can't use resistor greater than 10ohms as it…
