Hi Anthony,
Question:
can a set the bridge voltage to what I want?
Answer:
If you want to use the precision voltage reference for the input bias of INA125, you have four choices, namely 1.24V, 2.5V, 5V and 10V. You may select one of the pin connection…
Hi Giuseppe,
I suggested to use 300kOhm pull down on both sides of input. The error of the modification is about +/-0.1%, which is within the range of the Gain error.
If you do not like the solution, you may place a zener at the output of INA125 output…
Part Number: INA125 Hi,
I have a question concerning the reference circuit on page 10 in the datasheet. I use the INA125 Microcontroller
for reading a Wheastonebridge with strain gagues. What is the value of the load I marked red? Furthermore I want…
Generally, compensating such an offset is done at the bridge, by adding a fixed shunt resistor to one of the two adjacent arms on the same side of the bridge. The resistor type would be ideally selected to match the tempco of the bridge, or you can use…

Part Number: INA125 Other Parts Discussed in Thread: INA826 , ADS7142 , 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 of sensor…
Hi Siddhi,
Q: I am using load cell (strain gauge and I want to calculate the Vout . The formula given is Vout = G·(V+in – V-in) + Vref , but I can’t find the V+in and V-in in the product datasheet?
You stated "V+in and V-in represent the voltage applied…
Part Number: INA125 Hello,
With INA125, the cell voltage is pin-selectable. Do we have any recommended schematics, how to change the cell voltage in another way (on system level), e.g. by some MOSFETs?
Thanks
Part Number: INA125 Hi,
can anybody tell me the difference between INA125U and INA125UA? Where can I find
this information in data sheet?
Best regards
