Part Number: INA-CMV-CALC Hi Team,
My Customer would like to know how does one get unlisted instrumentation amplifiers into our Common-Mode Input Range Calculator and test them?

Hey Preetham,
Using an INA device on a single supply and common mode near ground can be challenging. It is a balancing act between the common mode voltage and the reference voltage. To help aid in the discussion we have an Engineers Calculator (link below…
Hi Taku-san,
The INA823 is one possibility available on the SOIC, pin compatible with the device you list above.
The device is specified over the extended temperature range -40C to +125C (but not above +125C).
Regarding the instrumentation amplifier linear…
Hi BongJo,
Thank you for providing the schematic and waveforms.
Looking at your schematic, I can see that you do not have a power supply decoupling capacitor connected to ground at the negative power supply terminal. If you apply a voltage other than…
Hello,
I have put the circuit into Tina in order to better understand the design and help guide our discussion. Below I am getting a gain of 1.94 dB and this aligns with the expected calculated value. I have modified the circuit such that the reference…

Hi, I have been interested in simulating the diverse INAs (Vcm vs Vout). Supposedly, there is an app that allows one to simulate the common mode diamond output, but link appears to be broken. http://www.ti.com/tool/ina-cmv-calc

Part Number: INA332 Hi,
I'm looking for a design tool that used to be available on
https://www.ti.com/tool/INA-CMV-CALC?keyMatch=vcm%2520vs%2520vout%2520calculator&tisearch=Search-EN-Everything
It's a software tool that calculates and plots…
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.
1)To ensure…
Hi Rodrigo,
Here is our INA Common-Mode Input Range Calculator for Instrumentation Amplifiers. The IA calculator may be very helpful in part selections and design.
