Part Number: INA819 Team,
my customer has issues with the model for INA819. The model does not provide expected output if the model is supplied with a single supply. (For example: 5V DC) The datasheet mentioned the device is capable of operating at single…
Part Number: INA818 Other Parts Discussed in Thread: INA819 , Hello,
I would like you to confirm about below.
* Could you please tell us difference between INA818 and INA819 ?
According to datasheet, it seems that differences are only following two. Is…
Part Number: INA819 Hi E2E,
Good day!
Checking the simulation model of INA819, the pin is not matched with the pin numbering indicated on the datasheet. Would this have an effect on the simulation?
Thank you for your usual support.
Best Regards,
Fr…
Part Number: INA828 Other Parts Discussed in Thread: INA819 , , INA821 Hi
The gain error vs temperature plots on the datasheets for INA819 (Figure 31) and INA828 (Figure 29) showed more than 10x differences, assuming these are typical. However, Gain vs…
Hi Martin,
I recommend to use TINA-TI. This is an easy-to-use and free Spice simulator which can be downloaded here:
https://www.ti.com/tool/TINA-TI
This simulator can also be used to draw schematics
On the products pages you will find Spice models or…
Hi Hailiang,
If you are considering the max. gain error < 0.1%, then we may have to go with INA819 or INA821 IA.
Both INA819 or INA821 are suitable for the requirements, but it comes with a higher cost (INA826 is low cost part). As the drop in replacement…
HI Aida,
The INA116 is a legacy device and it is not recommended for new designs. The INA121 FET input, low power, instrumentation amplifier is a possible replacement.
The INA121 has lower offset and higher CMRR with half the power consumption:

Hi Rick,
Is there another chip I can use with the same pad or socket
It looks like INA819 SOIC-8 part are in stock in TI e-store, and you may use it as p2p replacement.

Part Number: INA116 Other Parts Discussed in Thread: INA819 Hello,
I would like to know if is there a replacement for the INA116, which still has the Guard pin.
I see several replacement (like the INA819), but they do not have Guard pin.
Is there another…
Other Parts Discussed in Thread: TIPD191 , INA819 Hello!
We are exploring the using sinusoidal AC excitation for bridge circuit (not bridge chopping), and removing all DC offsets through AC coupling the inputs of instrumentation amplifier or using a DC restorer…
