Hi ADA team,
I'm using ADA4940-2 with ±VS = ±5V
What is the best connection recommendation for EPAD in terms of thermal dissipation and guarantee safe work?
Should I tied EPAD to GND or -Vs? In terms of heat absorption my PCB GND plane…
I have a question about the DISABLE pin of ADA4940-2.
I use the ADA4940 in +5V power supply.
I connect the DISABLE pin to +5V.
The DISABLE pin is connected with the pull-up internally.
Additionally, may I connect the DISABLE pin with +5V on…
Do you have an RC low-pass filter between the ADA4940-2 and your ADC? It would be great if you could provide your circuit schematic.
You can also try the free ADI DiffAmp Calculator or the NI Multisim Component Evaluator – Analog Devices Ed…
I am designing ADA4940-2.
I would like to add low pass filter for ADA4940-2
Regarding to "DRIVING A CAPACITIVE LOAD" and figure 71, we can set the RC filter with series R and CL.
I would like to set 400Hz as cut off frequency.
I have a question about the ADA4940.When the power supply is not turned onHow is the absolute maximum rating of VIN?
We ordered the chip ADA4940-2 and its bare evaluation board UG-018 (http://www.analog.com/static/imported-files/user_guides/UG-018.pdf), but we have no clue where to find the bill of materials of that board. Could someone help tell where we…
So... I had the wrong feedback pins connected on the Macromodel. I conned FB- to IN- for instance. connecting FB- to IN+ and FB+ to IN- resolves my issue
Seconding this answer. FDA has a unique transfer function from a normal op-amp.You can check it out on page 21 onwards of the ADA4940 datasheet.
Hello! I want to use ADA4940-1 to drive AD7768-4. Can it work normally if it is not driven by an operational amplifier before ADA4940? What's the impact?
