1. The spec table has min, typ and max values for a comparator with built-in hysteresis. Example is AD790.
2 and 3. The external hysteresis set by the user will overwrite the internal hysteresis. Please refer to page 4 of this document.
AD790 太慢了。。。。。。。 40ns
Apologies for the late reply. You can use AD790 for converting your sine wave to square wave.
You can use the circuit below as reference for your application. You will just need to set pin 8 depending on the absolute value of your voltage at the…
Thank you very mach for your quick reply.
I understand that + mark means the bias current flows into and
- mark means the bias current flows out of the device in your datasheets
which means the AD790 bias current flows into.
And we have…
we are using AD790 in one of our product "loadcell Transmitter ".
The problem we are facing is when loadcell is disconnected we are not able to warn to user .
I know if the voltage is 0 or full scale something happen but when loadcell…
The AD790 will handle 10V p-p. It's a 1990s vintage part.
your considerations are correct. The feedback resistor R1 in hysteresis.jpg is times higher than R2.
For you hysteresis you can replace one of these resistors by a series connection of a fixed resistor and
The AD790 is not…
I was trying to simulate the AD790 in multisim for awhile now, and t seems to be failing.
So, I am turning to the community for this one. Posted is the circuit that I will be using for my DDS. Would someone be willing to double check…
