HI Priyanka,
I assume you are referring to the INA849 as shown on the title of the post, and INA848 in the description above is a typo, since you require gain=1V/V, and the INA848 has a fixed gain of 2000V/V. Let me know if this is not the case.

Part Number: INA849 Other Parts Discussed in Thread: ADC3643EVM , , INAEVM-ALT-SO8 , ADC3643 Hello TI Team,
I am currently working on the INA849 that I would like to use to feed the input of an ADC3643EVM board.
It is connected to a square wave generator…
Part Number: INA333-Q1 Hi team,
Could you tell me which EVM and how we use it for INA333-Q1 evaluation?
Is "INAEVM-MSOP8" suitable for INA333-Q1 VSSOP? Is it EVM without INA device and we need additional INA333-Q1 IC itself to evaluate INA333-Q1 with…
Part Number: INA333 Hi,
I'm using INAEVM-MSOP8 to test INA333 with below configuration. V+=2.5V, V- = -2.5V. REF=0V, RG=1K, which sets GAIN=100.
Although IN- is not connected to GND, but I measured the common mode voltage is only 0.6mV.
IN+ -IN…
Part Number: INA333
Hi,
I'm using INAEVM-MSOP8 to test INA333 with below configuration. V+=3.3V, V- = 0V. REF=0.3V(not to GND shown in the picture), IN- to GND is 1.65V(add a 1.65V reference from IN- to GND), RG=536ohm, which sets GAIN=187.

Hi Manoj,
I did not find specific TC EVM, but we have universal instrumentation Op Amp EVB, which it will make your design slightly easier.

Hi Ian,
Thank you for suggestion on VCVS1. It makes sense.
I was wondering if its possible to do a bench measurement of the CMRR with a function generator and oscilloscope. Where can I find guidelines to do so ?
I also have the INAEVM-MSOP8 evaluation…

We do have an EVM that should work with this part. You can order it here:

The INA317 is relatively new and doesn't have spice models or reference designs done yet, however the INA333 is very similar in function and…
Hello Carlos,
Here are some questions/observations for you:
1) What are the supply voltage(s)?
2) Please make sure that you are measuring the input voltage, reference voltage, and output and the physical pins of the device. By this I mean that…
