Part Number: INA122 Tool/software: I intend to measure the difference in voltage using the INA122 and generate an output with an offset of 1.425V running on a +2.85V supply.
With no input or 0V between J7 and J8, the output of the IA is 1.426V
With a…
Part Number: INA122 Other Parts Discussed in Thread: INA350 , , INA321 , INA155 Hello,
What is the best in stock cross you'd suggest for the INA122U? Would you be able to confirm the difference between INA155U vs INA155UA?
Thanks, Adam
Other Parts Discussed in Thread: INA122 , LM27762 , LM27761 , LM7705 , LM2776 I've been working with my TI INA122 with a couple of sources. The configuration for this issue is single supply with pin 4 grounded, pin 3 held at 3.3V, pin 5 held at 2.5V, and pin…
Part Number: INA122 Other Parts Discussed in Thread: INA333 , Hello everybody, I have a big problem with my INA122P amplifier. I put force sensor (CZL204E) to determine the mass on it. However, the voltage was too low. So, I decided to use a wheatstone…
Part Number: INA122 Hello Team,
My customer is using this chip to filter an analog sensor signal with voltage rails of 0 and 5V with a gain of 5 (open circuit gain resistor). Unfortunately in some scenarios the IC may be subjected to slight impact or…
Hi Dave,
Yes, If your customer wants to leave 10.00V excitation voltage alone, then one of the option is to change two resistor values. I am talking about the minimum modification at this point.
The INA122's input Vcm voltage is changed from 4.97Vdc to…
Part Number: INA122 Other Parts Discussed in Thread: INA133 I have a 50kg loadcell being amplified by an INA122 but it doesn't output any (or enough) voltage at low force. If I increase the gain (variable resistor) to register the low force then it maxes…
Part Number: INA122 Hi
we have microfabricated some thermistors, however the gain is still in microvolts and we are using an INA122.
Would you recommend cascading another INA122 or some other amp? is the any circuit from the

Part Number: INA122
Original details: On a properly functioning circuit measuring from either the LoadCell In- or the LoadCell In+ to ground with no power applied will result in a reading of 75K ohm. On a failed circuit the measurements results in a reading…

I am testing the circuit below. The 100Ohm shunt is used to measure current and the 36kOhm simulates a 100uA load. However the output is always around 2.7V instead of the expected 1V output…
