Part Number: INA188 Other Parts Discussed in Thread: OPA387 Hi, in datasheet sector:
7.4.3 Input Bias Current Return Path
The picture shows that we could connect 10kohm between one input to GND.
But I think in this case the common mode input voltage is…
Part Number: INA188
Dear all,
I'm designing a circuit that uses INA188 as instrumentation amplifiers to measure some strain gauges. The strain gauges are not always connected to the INA188 amplifiers, so when there's no input they saturate either towards…
Part Number: INA818 Other Parts Discussed in Thread: INA188 , Hi team,
I saw INA818 has a smaller initial offset than INA188 at 25C. Considering the drift under 85C, is the total offset still smaller than INA188? I also saw discussion about long term dr…
Part Number: INA188 Other Parts Discussed in Thread: INA818 How to achieve 0.01% constant-current accuracy for DC power supply?
Should you also consider the input bias current vs temperature as well?
Part Number: INA188 Hi,
I want to level shift with gain an 2.5V mean, 1V p-p (1.5V to 3.5V) signal with INA188 instrumentation amplifier.
I want the output with 5V mean and 3V p-p. So I set gain resistor 25k to have 3 gain, and VIN- input to 2.5V. Also…
Part Number: INA188 Hello,
Regarding the INA188IDRJR (8-WDFN Exposed Pad) I would like to know what are the recommendations for the thermal pad connection to the PCB. On the datasheet there is no specific information about this subject besides that it…
Part Number: INA333 Other Parts Discussed in Thread: INA826 , INA188 , Hi Team, The customer is trying to model CMRR using INA333 INA188 and the INA826 that TI has datasheets for but things dont seem to be working properly and was wondering if it's to do with…
Hi Cyril,
your information is a bit confusing. Is it 4...20mA or +/-20mA or 0...20mA?
You will need to connect a negative supply voltage to the V- pin of INA188. Depending on your input signal current, a LM7705 might eventually be sufficient.

Part Number: INA188 Other Parts Discussed in Thread: INA819 Hi team,
In the Quiz, why the answer is C?
1. Answer B : I think the gain is set correctly from my calculation.
2. Answer C: I think It is very important to use a buffer because the input to…
Part Number: INA188 Hi,
I'm measuring a 10uA DC load with INA188. INA188 is powered by +-15V. I think Figure 16 specifies the AC CMRR. As the common voltage of INA188 is kept as 12Vdc, does it mean the error brought by AC CMRR could be ignored? I didn…
