Part Number: INA125-DIE Other Parts Discussed in Thread: INA125 , The white Noise Value for the INA125-DIE is listed to be 0.8nV/sqrt(Hz) in the part selection table in comparison to the 38nV/sqrt(Hz) for the INA125, but no separate data sheet is linke…
Raymond--
At long last, I've determined the primary source of the -4 to -6 mV/°C amplifier output drift--it was the (#$%&) strain gauges themselves. Despite selecting strain gauges that are CTE matched to the DUT (aluminum), there must be…
Part Number: INA125 Other Parts Discussed in Thread: INA826 , ADS7142 , REF200 , TINA-TI Hi
I'm implementing a readout circuitry for Wheatstone bridge based pressure sensor using circuitry shown below.
But we observed a loading effect at output pins…
Part Number: INA125 Other Parts Discussed in Thread: LM27761 Hi,
Can you tell me what will be the output if my inputs are floating?
I have set gain as 239.29
I have set offset as 0.2V
The supply is 12V
Used internal reference of 10V
Art,
For the circuit to work properly, customer needs to implement only one of the recommendations above and NOT all of them:
1. Reference the output voltage above the ground by connect IAref (pin 5) to voltage of 250mV or higher
IAref must be a low impedance…
Hi Rodrigo,
Rodrigo Alvarez said: What is the rational for choosing gains of 2000 * 20 on the INA and 2nd stage, vs. say 1000 * 40 or 4000 * 10? Is there a sweet spot that will minimize noise or other considerations?
As the bandwidth is no issue here I…
Part Number: INA125 V+in and V-in meaning
I am interested about Load Cell Millivolt (mV) Output Calculator for my application, and my product enquiry is... V+in and V-in meaning I am using load cell (strain gauge and I want to calculate the Vout . The formula…
Part Number: INA125 I am using the ina125 chips to make a load cell with six channels and the bridges have different bridge voltages gain etc, the ina125 chip is good as it integrates everything. I have a few questions.
1-what is the VrefBG pin 13 for…
Part Number: INA125 Hi,
I'm using the INA125 to amplify a strain gauge. This is the schematic:
the output of the INA125 goes into an analog input of a microcontroller. My problem is that when the strain gauge is disconnected, the INA125 output…
