  • Forum Post: Can't get the INA122 working correctly

    Ed Mauro Ed Mauro
    I'm trying to read the values off a CSLA2CD hall effect current sensor running off of a 9V regulator. The 9V regulator also drives the INA 122. The signal off of the current sensor sits on 4.5V (no current detected) and goes up as more current passes through the device. I'm using an INA22 to...

  • Forum Post: Problem with INA122P

    Rodrigo J���ger Rodrigo J���ger
    Hi guys, I've tried to test the circuit in the following picture, and even though it works flawlessly in the simulator, the amplification stage using a INA122P doesn't work as intended whilst mounted in a protoboard. The gain is not constant, it is falling as the input voltage increase, as you...

    Neil Albaugh Neil Albaugh
    Thanks, Alexandre. The IA shown in the Handbook is still a good one-- its common mode input voltage will go to zero and with a load of 20k the output will swing up to 50mV below the supply rail and down to within 100mV of ground. There are more modern 5V CMOS instrumentation and difference amplifiers...

  • Forum Post: Interferences and INA122

    Yaroslav Mudritsky Yaroslav Mudritsky
    Hi, I have a problem with my loadcell and ina122 output. My output is too influenced by interferences on loadcell body. Seems there are no(or very low) interferences on circuit or on cable. Cable is shielded and the shield is connected to gnd and on loadcell body. If i touch loadcell body (and hold on...
