Part Number: ADC3422 Other Parts Discussed in Thread: OPA656 , ADC3244 Hello,
Question for page 3 channel C.
1) Why D1 circuit needed as U1 has similar structure?
2) What's purpose of R22?
3) What's the purpose of R20+L4+R25+R21?
Question for page…
Hi Magnus,
You could use the THS4541 ADC driver in single-ended to differential configuration for driving the ADC3424. You could take a look at the below TI Designs for the THS4541 ADC driver schematic:

You bet Jacob, on that other topic of MFB filter design,
Yes, that early app note I did had the cubic coefficients when you include the the op amp gain bandwidth incorrect -

I had fixed that in building the online Intersil…
Laurent,
Here is a new TI design that shows use of the THS4541 fully differential amplifier as a DC coupled ADC driver. This signal chain could be used for a zero IF receiver:

Can you let me know the bandwidth you need for…
Hi Steve, I was on the THS4541 development team and have done numerous MFB filters using the THS4541. There were a few TI designs that illustrated some examples that I helped with. You can find these under the tools and software tab in the web folder…
