Hi Luca,
the output of INA2126 cannot fully go down to 0V. The output hangs in saturation and so you don't see a change with and without load on the load cell.
For the B-side problem you are violating the common mode input voltage range of INA2126…
Other Parts Discussed in Thread: INA326 Hello everyone.
I have been trying to get this instrumentation amp to work for a few hours now and I have no clue what I am doing wrong. I am using a function generator to input a sine wave (~20mVpp, 500Hz) into…
Other Parts Discussed in Thread: INA2126 , INA333 , INA326 , ADS1247 , ADS1118 , ADS1220 I'm trying to amplify the voltage from an RTD (resistance temp device) using one amplifier on INA2126 using a single 5VDC supply. The circuit is attached. The 0.1VDC…
Other Parts Discussed in Thread: ADS1211 , INA2126 Hi All,
I'm doing project on weigh scale application.
I'm using ina2126 and ads1211 in the analog part and im using one smps.
I'm getting following problems.
1. I'm not geting the stable counts…
Part Number: PSPICE-FOR-TI Other Parts Discussed in Thread: INA2126 Hi,
We are using pspice-for-TI concurrently with the CADENCE original software. We are also using in our projects custom made/third party SPICE libraries (.lib and .OLB) and we are…
Hi
i am trying to amplify the output from wheat stone bridge and facing exactly the same problem . the amplified output is just few volts less than the supply to INA2126,can you please suggest solution to this problem
Jerry,
There are a couple things I should point out. First, the input signal to the INA2126 is being applied as a common-mode voltage (same polarity at each input), instrumentation amplifiers are designed specifically to reject common-mode voltages…
By the way- I did solve this problem. The problem was that the two op amps (INA2126) used to interface the thermocouple had their input biases tied together. Since the leak off current required is extremely low I just added a 1M resistor in series with…
