Original Question: ADA4941-1 .cir by sss
Our customer tryed to simulate the ADA4941-1 with ADIsimPE.They downloaded the ADA4941 SPICE Macro Model from web linked page .
But the error occured with following error massage.
"*** ERROR *** The circuit…
I am getting data from an AD7961 ADC with an ADA4941-1 in front as a single-ended-to-differential stage.
I am getting a surprising noise of +/-2mV when I short the ADA input to ground. This noise goes down to +/-0.2mV if I skip the ADA4941-1…
Thank you very much for your reply.
The provided information is really helpful to me. As you suggested I have decided to use ADA4941( similar to ADA4940 ). I am using ADA4941 (single to differential converter) as similar to the architecture…
What is the difference between the ADA4940-1 and the ADA4941-1? They are both ADC drivers, but what distinguishes the two parts from each other?
I am considering Sallen-Key, Low-Pass Filter like figure 54 on the datasheet.
There is a situation that the input is opened.
Then the output would be unstable.
Should I put termination resistor?
If yes, which value can I use?
There is a little…
Hello, while measuring the specs of a measurement prtotype, where at the end a ADA4941 drives an AD7691, I noticed that the outpunts of the differential amplifier are in phase. I could not detect shorts and measuramnts were taken with and without…
ADA4941-1 could not handle Input Voltage of +10V since it is limited to an IVR of -4.8 V to 3.9 V. You will be needing an attenuator after the transducer to step down the voltage at a level acceptable by ADA4941.
Apologies for a delayed response.
Yes you can use ADA4941-1 at bipolar inputs with single supply, PROVIDED that there is enough DC bias for the inputs. ADA4941-1 is guaranteed to work with an input common-mode voltage range of 0.2 to 3.9…
