OK. So the INA849 comes in 2 versions: SOIC-8 and VSSOP-8. Are there any evaluation boards for the VSSOP-8 version? I guess not. :-)
I just discovered a variant with a fixed gain of 2000: INA848. It has CMRR = 132, whereas INA849 has CMRR = 120. But INA848…
Hi Adam,
Adam Steele said: I am looking for any advice (even obvious stuff) as it is the first time I'll be using this component or making a circuit like this.
You may try the following circuit, see the simulation file. Here are several highlights…
Hi Zac,
zac zhang said: how is its value calculated, and how to consider the stability of the first stage circuit here?
OPA637's datasheet is specified GBP at 80MHz. Based on the simulation below, Gains = 49.505V/V and the pole at -3dB = 1.78MHz. The simulated…

Part Number: INA826 Other Parts Discussed in Thread: LM358 , ADS1299 , INA851 , INA848 HI,
When we applied the INA826, we found that there is a certain DC component in the input differential mode signal.
Please send us the reference design or information…
Hi Maheswari,
when i am simulating the without the VCM i am getting the noise signal.
Could you share the noise simulation plot with us? I'd like to know what part noise signals you are having issues with.
Below is an example of ECG simulation. It…
Hi Paride,
The sensibility of my system is 0.38 mV/V on maximum load
Yes, the application will need to maximize excitation voltage in order maximize the overall change, which is approx. 1.9mV or 0.1815Ω in delta of the load cell.
In this case, I…
