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: TIDA-01063 Other Parts Discussed in Thread: INA188 Tool/software: I have a question regarding this design.
In table 7, it is stated that the PCB Rogowski coil input is 10.7 μV to 1.07 mV (for 10 A and 100 A). VBIAS is also set to 1.25V.…
Thank you for the simulation file. I am adjusting the gain of INA188 , reference voltage as per my application. when the load cell voltage is -1mV, INA188 should amplify this to 1.5V. when the load cell voltage is 11mV, INA188 should amplify this to 7…
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 Riaan,
I picked I NA188 as the IA. You may operate at 10Vdc, 12Vdc, 15Vdc or 24Vdc, but use LDO to power the part, instead of SMPS. You can use SMPS to step down the voltage, say 14-15Vdc and use LDO to further get rid of ripple voltage and switching…
