I have a quesion about AD8691.
Looking at the input voltage range of the datasheet, it says +3.9V(Max) at Vs=5V.
And also this is specifired at T A = 25°C.
I need information on input voltage range when Ta is between -10℃ and +50℃.
Do you have the data on that?
Over the temparete, how much do you think input max range would change?
Thanks in advance.
I will ask the applications engineer of this device if the information you need is readily available.
I will get back to you soon.
I just confirmed from the application engineer that the IVR max at -10 degree C would be about 3.7V. At +50 degree C the max IVR will typically increase less than 1V. It is just an estimate and is not guaranteed. It is recommended that you should not exceed the guaranteed limit of 3.9V max IVR.
Hope it helps.
I'll check the behavoir on the board.
