I have a question about the ADA4940.When the power supply is not turned onHow is the absolute maximum rating of VIN?
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…
Hi, I am having a very similar problem to the person in this thread...http://ez.analog.com/message/124234#124234
I'm using the ADA4940-2 with unity gain (Rf = Rg = 499R) to buffer 2 differential voltages from an RF demodulator. I'm using a 16-bit ADC…
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.
Hi Dougl, Thanks for you reply.
I didn't read AD9633 datasheet carefully, however, someone told me that AD9633 is not like AD9218 which has its own VCM output. That means external reference source for voltage bias for ADC and VCM for amplifier is required…
To get a gain of 100dB with 500kHz of bandwidth you will need a minimum of 2 op amps. I suggest you look at the ADA4940-2.
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…
I'd like to use the ADA4940 as an ADC driver. The input to the ADA4940 is from another circuit that can be powered while the ADA4940 is unpowered. The input to the ADA4940 will be from a single-ended source at +/- 2.5V maximum. I'd like to know what…
ADA4940 is very low power; obviously this is the up-side. Not surprisingly, there are some trade-offs. The main compromises compared to the ADA4930 are:
