Hi,
I'm trying to find what is the minimum required supply voltage for this component.
In one place of the datasheet it is stated as ±2.25, but in another place it is stated as ±1.5.
Which is it?
My application is to run this from a 3.7 V battery, and can in principle use either +3.7 V (minus some losses) or from a buffered mid-rail at ~ ±1.65 V.
Hi Tamara,
Nice title you have there, there should be more of those around.
Thank you for clarifying. What was surprising, is that (in some place, I can't find at the moment) INA828 was suggested as the new replacement for INA118. That just seem highly suspicious since they operate on different voltages and different supply currents. Either way, the requirements are as I highlighted in the list above. Something like the INA 819, but with a lower supply voltage. Do you have such a thing?
The suggestion for INA317 is surprising as it has 6 times the noise level as the one I'm trying to replace (828) and 5 times the offset voltage of the 819 or 333. In fact both the 819 and 828 would have been perfect, was it not for the high supply voltage (>1.8). In addition the data shown below is impossible to understand. How can the offset error be 2.5 times the value?
