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 Other Parts Discussed in Thread: LM7705 , REF3312 Hello Guys,
Good day.
Our customer is having an issue with the INA125. Below are the details and the attached schematic. Appreciate your inputs on this.
They feed device with 3V They…
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…
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…
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
Fabian
Part Number: INA125 Other Parts Discussed in Thread: INA818 , INA188 Hi,
i couldn't find maximum ratings in the datasheet of the current for the V_Ref_Out pin in order to calculate the minimum resistance
of the Wheatstone bridge for a load cell application…
